1 An Optimization Research of Urban Image Construction and System Structure Characteristics based on CIS Wang Tingting Department of Art and Design, Hefei University, Hefei , China Abstract In the process of urban modernization, shaping a distinctive city image plays an important role in urban development. In this paper, the author makes an optimization research of urban image construction and system structure characteristics based on CIS.Urban CIS is a unified city image design body, in the city image construction, pay attention to the optimization of various identification elements, so that these micro elements can be integrated, from a macro perspective to reflect the overall image of the city. In the formulation of urban development planning, we should set up a long-term vision, and take the shaping of urban image as a long-term process and coexist with the socio-economic development. Key words: City image, GIS,Spatial data management system, Urban CI structure 1. INTRODUCTION Under the influence of the standardization of the modern industry, the image of many cities in China is weak, and ignores its own characteristics. This simple and blind "reproduction" caused by the weak city identification, has aroused the concern of the community, but the professional field of research is still to be further (Choi, 2008; Jankowski, 2015). The concept of structure of city image system, the city construction concept, behavior and visual physical environment and visual elements of standardization, symbolization, structured, and model, make the development of city image system of the formation of structural optimization and integration, to build a bridge to the public mind and eyes. Geographic information system is a new subject in 1960s rise, computer and geographic information science is the combination, in support of the computer software and hardware, using the theory of system engineering and information science, scientific analysis and management connotation of space geographic data technology system to provide for the planning, management, decision-making and research needs of information (Kapetanakis, 2014; Mora,2014). Provide the geographic information system is the main raw data and the low level of information, provide data support in decision making in GIS only, and does not provide substantive decision, decision problems are difficult to solve the complicated structure. Geographical information is a general term for the number, quality, distribution, interaction and change law of the elements of the geographical system. Geographical information belongs to the spatial information, and its location identification and data link, which is different from other types of geographic information (Tassinari, 2011; Skelton, 2014). It is the most significant sign of information. The location feature of geographic information, geographic coordinates is established by latitude network or highway network to realize spatial location identification, geographic information also has the characteristics of multi-dimensional structure, which based on multi feature in two-dimensional space in three-dimensional structure. 2.GIS SUPPORTS URBAN DESIGN Geographic information system is a computer system to collect, store, manage, analyze, describe and apply the whole or part of the earth's surface and spatial and geographical distribution of the data. It is composed of hardware, software, data and users. Its main function is to realize the collection, editing, management, analysis and statistics of spatial data. The role of geographic information system is the most important for quantitative analysis of statistics and related information of geographical space, its biggest characteristic is that it can make the earth surface space location and characteristics of things together organically, and through the computer screen, visually displayed (Yasmin,2015; Suyoto, 2015). This feature makes the geographic information system has a wide range of uses. With the accelerated process of information, the field of urban planning will be more and more use of GIS technology, the application of GIS technology to urban planning has brought a broad space for development. The traditional data analysis, mapping results and a series of process that involves the processing of city spatial information can be used to place GIS technology, GIS technology and traditional methods or means, has the advantages of There is nothing comparable to this. The use of GIS technology and remote sensing technology can promote the analysis from qualitative to quantitative and more planning, the overall design of the traditional city form mainly qualitative analysis, the lack of a unified and standardized criteria, therefore, various elements of the GIS integrated analysis of city form the overall design to the 507

2 formation of a relatively perfect system the form of city design, to provide efficient quantitative analysis tools, to support the overall design scheme of city form a scientific and reasonable. Figure 1.Geospatial Database Geographic information system is a kind of spatial data management system, which is a kind of special and very important information system, which is based on the computer as a tool, and has the function of geographical pattern and spatial location. The data processed by geographic information system includes two categories: spatial data and non-spatial attribute data. Spatial data refers to the data of natural, social and human economic landscape, which can be used as a reference to the natural, social and cultural landscape. They can be input to the geographic information system through the digital instrument, the scanner, the keyboard, the tape recorder or other input devices. Spatial analysis is a spatial data analysis technique based on the location and shape characteristics of geographical objects. Spatial analysis is the basis of all kinds of comprehensive geological analysis model. By using the spatial analysis technique, we can gain new experience and knowledge by the observation and experiment of the original data model, and then it can be used as the decision basis of spatial behavior. Figure 2.GIS software Mapobjects 1) System interoperability: Interoperability of GIS also refers to data standardization; interoperability of geographic information systems can be understood as GIS system integration platform, it realizes the communication and cooperation between the system and its application system in heterogeneous environment, to accomplish a specific task. 2) Data cube: The GIS data only to adapt to the modern requirements for multidimensional development can generally reflect the three-dimensional, multi-dimensional, before the research focused on the design of 3D data structure, optimization and implementation, and the application of 3D visualization technology, system function and module design etc.. 508

3 3) System modularization: The modular GIS is the geographic information system of object oriented and component technology, the function modules of GIS for multiple controls, each control to perform different functions, integrated through visual software, the formation of the final GIS applications. 4) System intelligence: Providing decision support services is the embodiment of GIS system intelligence, and this is particularly important at present, the current research focuses on how to combine the research results in the field of decision support with GIS. 3. CITY IMAGE SYSTEM 3.1. Concept of urban image system City image system refers to the planning and design under the guidance of all aspects of the city image and with the help of diffusion media or other channels. So, it is aim to form a unified system engineering value for the city view of highly personalized features in the public mind. The city is a big system, the city image system is one kind of cultural expression form in this system, this has been doomed the city image system is a complex social system. The establishment of the urban image system involves many fields, such as politics, economy, culture and so on, which is a huge system. System is an integral part of the organic connection of the urban image system, including the urban management concept, the city's main acts and the city's overall perception of the three subsystems. Figure 3.the constitution of City Image System City image promotion is based on the integration of city image system of internal subsystems, establishing the concept of city construction and social development of the city, at the same time in order to unify and standardize the behavior of the city landscape performance and visual expression, so that the development of the various elements of the city more harmonious and stable, so as to make the city construction more standardized. Because the city image system involves all aspects of the city, so it must follow the principle of the whole system and structure in the process of city image promotion in the interactive relationship between the various subsystems to fully focus on mutual restriction and mutual effects. The organic connection between the elements becomes the foundation of the system structure of the city image City image system structure "System theory" in the definition of structure is: "refers to the system within the various components of the relative stability of the contact, the organization of the order and its spatial and temporal relations in the form of expression". According to this definition, the structure of the system depends on the elements of the system, the relationship between the formation of these elements and the integration of the performance, and by such a comprehensive led to a system of the overall provisions. The structure of city image system reflect the internal relationship of the system, is an internal system, reflects the elements in the system of interrelated constraints, it 509

4 is because of this contact and restrict each other to make the system have the overall behavior, the integrity of the system has become the reason Urban CI structure The image of the city is an open complex system, as a whole, the diversity of complexity not only from the system, more important is the interaction between the various subsystems, which are produced by the interaction of the relationship and the relationship between the integration of elements constitute the basic structure of city image system.using system optimization theory, this paper puts forward the concept of urban image system structure from the perspective of urban system. The so-called urban image system structure (CI structure) is an organic whole which is formed by the interdependence and mutual restraint of the urban image system elements in a certain time and space. As a summary, the city CI structure can be expressed as the relationship between the elements and the interaction, "the relationship between the expression" and "the mechanism of action" has become the core content of the city CI structure Characteristics of urban CI structure The structure is manifested in the coordination and unification of the relationship in the organic body, and it is the reaction of the inherent order of the system. The generation of order is the result of the complex function of the system, the inherent complexity of the system makes the system structure constitute the integration of the process, and the performance of a number of dynamic transformation system". This transformation system has the characteristics of integrity, and it is embodied in the stability of the organization structure. The structure of urban CI is the integration of various relationship patterns in this transformation process, which has the integrity of structure, the structure of organization, the complexity of structure relation, and the transformation of structural system Functional performance of urban CI structure Function refers to the nature, ability and effect performance system and the external environment and the interactions between the external manifestation system of relatively stable internal contact, order form and space organization. The construction of city image system is a kind of structure, and it must have its functional performance, which is mainly reflected in the: (1) The relationship between the elements of the city CI and mutual restraint; (2) The logic level of the construction of urban CI; (3) The strategic development of the medium and long term city brand in the construction of urban CI; (4) Structural framework and theoretical basis of urban CI strategy; (5) The effective ways and means of accumulation and increment of intangible assets in urban CI; (6) The operation mode of urban CI cultural capital The target form of urban CI structure The structure reflects the relatively stable contact way, between the system elements of the organization order and its temporal and spatial forms, namely the structure of the system is relatively stable, the structural stability of CI city is reflected in its target form, set up the city image system to achieve the goal of city development goals, including the goal, the main city cultural city quality objectives city image target. 4. INTEGRATION OF URBAN CI STRUCTURE RELATIONSHIP MODEL 4.1.City CI structure relationship Because the city image system involves all aspects of the whole city, so we must follow the principle of system and structure in the process to enhance the image of the city in the full emphasis on the interaction between the subsystem of mutual restriction and mutual effects. City image elements of the system mainly includes city management, city and city overall perception behaviour between the three part, city management idea, behaviour and overall perception of the three elements of mutual connection, mutual restraint, the formation of triangle stable structure: city management idea dominates the behaviour pattern and city cognitive way, behaviour and the whole City perception is the realization of the dynamic and static city based business philosophy to; at the same time, can give the city to emotional expression through cognitive behaviour, cognitive style can turn through the city to guide the behaviour of the subject towards the direction of healthy development. 510

5 Figure 4.Factor relation of City Image System Structure 4.2. Urban CI structure model The pyramid principle In the literary world, Barbara point out the "Pyramid principle": the brain automatically information to the different groups of Pyramid structure, in order to understand. Any thought in the pre - return to Pyramid structure is much easier to understand. This means that any written document should be consciously organized into the Pyramid structure. The core of the theory is: first, put forward the theory of the summary, and then put forward the concrete idea of the summary Hierarchical model construction in Pyramid Based on the construction of theoretical model of CIS structure of the city this principle: Pyramid hierarchy model, namely: first proposed city macro management idea, in view of the city planning subject behaviour, finally implement the static visual micro specific communication. Figure 5.Pyramid Hierarchy Model of CIS Structure In planning the design, the different levels of city image elements in Pyramid structure, a city management system to guide the whole image of the city at the macro level of control operation, level norms constitute the dynamic image of the city operation, while the micro level is a static basis convey the image of the city operation; on the other hand, is the projection of Pyramid a hierarchical model of the formation of a concept system of city management for the whole structure of the core and foundation of the kernel structure and external radiation; the main behaviour of the system in the performance of the structural meaning to stabilize the 511

6 structure and control system of material properties, function level and range of effect; visual perception system reflects the kernel structure of the existence and representation of external performance in turn, the external performance and constantly adjust and affect the existence and development of city image system. In the cultural function, its core structure is formed by the inner and outer core cultural level, the middle layer and the surface layer Structure model expression Through the construction of the Pyramid hierarchy model, we can understand the deep connotation and extension of the urban CI structure more intuitively. The expression of the structural model we summarized as "1334", that is, from a support kernel, three levels, the formation of a positive projection of the three cultural systems and the four surface of the Pyramid level model. 1) A kernel: The Pyramid hierarchy model of urban CIS structure is supported by a core structure, which is from top to bottom: urban spirit, human and nature.the so-called "urban spirit" is the value of the existence of the city as well as the existence of the city to bring us a spiritual sustenance and trust, the image of the city construction is to strengthen the city in the minds of people with a sense of identity and belonging.the so-called "people" is to respect human nature, people-oriented. The construction of city image is to respect the needs of the people in the city, the habits of the people, the tradition of the people and the relationship between the people and the people.the so-called "natural" is to respect our survival of the land. 2) Three levels: Construct the three control levels of urban CI structure, that is, the micro level of the city, the level of the middle level of the city and the level of the city's macro control.the micro sense level is the dominant structure level, which is made up of the City material, mainly refers to the cognition and understanding of the City material layer, which is the most direct expression of the city image;the middle level is the middle structure of the city's behaviour culture, which mainly refers to the standard and guide of the city's main behaviour, and is the management layer of the city image;the macro control level is the invisible structure formed by the urban immaterial elements, mainly refers to the orientation and expression of the urban management concept, and is the ideological level of the urban image system. 3) Three cultures: From the structure model, the core structure of urban CI structure can be obtained. In the cultural function, the inner core structure is formed by the inner outward radiation, which is the core culture, the middle layer and the surface layer.urban material culture is the surface culture of urban CI structure, which is composed of external, visible and visible infrastructure.city system culture is the middle level culture of city CI structure, and it is an entity of city culture.urban spiritual culture is the core culture of the city CI structure, including the city's knowledge, belief, art, morals, customs and all the ability and habits as the city people, is the core elements of urban culture. 4) Four expansion surfaces: From the four main aspects of the city's policy, development, culture and image, the theory framework of the structural model of urban CI is constructed. The organic integration of these four aspects constitutes the city's comprehensive competitiveness. Urban policy power mainly includes three aspects: the city's decision-making power, the executive power and the government's image; City development it is a comprehensive system, including the development of city economy, enterprise development, social development and city brand competitiveness of city on the basis of the formation of the city's comprehensive competitiveness; Urban cultural power mainly from the perspective of urban cultural capital accumulation and operation, in order to enhance the cultural connotation of the city image; The city image force mainly includes the city brand management, the city environment cognition and the city image design and so on Structural model evaluation principle 1) Holistic principle: City image design is the overall design of the city image system of all kinds of elements, designers should fully consider various factors interact with each other and organic whole, overall grasp of the overall planning, the city image system of the formation of structural optimization. 2) Stability principle: The concept of city management, the main body of the code of conduct, as well as the city's overall perception system design should be balanced, coordinated development of the three indispensable. 3) Structure optimization principle: City image system design is not a step in place, but to go through repeated practice, exploration and summary of the process, only in this way can ensure that the city CI structure is gradually reasonable and optimization Structural urban CIS model New mode of transmission: City brand image is a kind of city overall innovation, the ultimate goal is not only to show city image communication of the external image, the deeper meaning is to meet the growing city 512

7 of the whole city living environment, work environment, development environment requirements. We can promote the image of the city by the media, major events and other ways of radiation, the image of the city to carry out tangible or intangible impact. Only through the spread of the city image to produce value, only through the spread of the design can produce value, especially economic value, the city image of the intangible assets to produce benefits. New development model: City image design management (City Image Design Management, referred to as CIDM) is the image design activities as an important part of city cultural image in the capital operation, decision management, behaviour management, system management, interface design of image design series of management, good at using the design method, implement the design oriented thinking and behaviour, and the process of the city is transformed into productivity and competitiveness. The basic elements of the framework of the theory are: design decision-making, design organization environment, design project management and design innovation, etc.. Design and management of city image in China is still lagging behind, with the deepening of reform and opening-up, the continuous improvement of the market economy, the increasingly fierce competition, design management is an organic system of city image construction undoubtedly lead to the healthy and orderly development. New cultural model: The process of city image communication is a process of "transforming business city" to "city marketing", city cultural communication model is created from the "city cultural capital" the sense of creation and management of city image and cultural resources, this business model than the economics of operation is more rational and cultural asset substitutability and creative cultural resources. 5.CONCLUSIONS The construction model of city CI structure theory, straighten out the relationship between the various elements of the city image system, grasp the city planning CI from management to the behavior of the final implementation of the overall perception of system design has the logical relationship, can provide a comprehensive and systematic structure model as a reference for the construction of city image, the city image construction in health system under the guidance of structural and orderly.
