Abstract: Promoting coordinated of resources and environment is an important aspect of building a harmonious society and ecologically sustainable civilization. Here we provide scientific basis to promote the of ecologically sensitive civilization, via a mathematical statistics method that calculates the degree of coordinated. This model is of great practical and social significance, providing strength to research around coordinated of resources and economy. Based on evaluation of characteristics of the present resource environment and economic of Shandong Peninsula city group, a coordinated measure of resource environment and economic was calculated. Overall, the highest measurement was found for Weihai, followed by Yantai, Qingdao, Ji nan, Weifang, Rizhao, Zibo and Dongying. According to evaluation results of measures for each city, we put forward suggestions for sustainable of Shandong Peninsula region. Keywords: Shandong Peninsula; Urban Agglomerations; Resources; Economic ; model; Sustainable Introduction An outcome of the United Nations World Conference on the Environment and Development held Rio De Janeiro in 199 determined a strategy for global sustainable (United Nations, 199). Although the current interpretation of the concept of sustainable is not wholly agreed upon by scholars, yet the core of the theory is consistent, being the coordinated of the social economy (Ec), resources (Re) and the environment (En). The coordinated of Ec-Re-En comprises the core of sustainable. Furthermore, the degree of among Ec-Re-En makes up the quantitative indicators of coordinated,. * WANG KUI-feng (1981- ), male, PhD, senior engineer, mainly engaged in geological resource and geological environment evaluation and research at present. maplewkf@16.com 0 64 which are used as the assessment standards of sustainable. The Communist Party of China (CPC) 18 th National Congress s report made it clear that faster action is required to set up a system that can protect the ecological environment, improve institutions and mechanisms for developing geographical space, conserve resources, and promote modernization that features harmonious between the man and the nature (HU Jin-tao, 01). Many scholars have dedicated qualitative and quantitative research to the relationship between the resource environment and economic. Mutisya E and Yarime M (014) evaluated the degree of among environmental, economic, and societal factors in the management of in Kenya, proposing a among all three is necessary to achieve sustainable outcomes. Other authors have used a coupling dynamic method to evaluate

In China, a number of scholars have conducted evaluations of the coordinated of the ecological environment and the economy. By analysing interactions and relationships between groundwater and environmental, social and economic factors, WANG Hai-ning et al. (01) established a quantitative evaluation model for the coordinated of resources for five administrative districts in Guanzhong of Shaanxi Province, using a minimization of deviation coefficient. For Gansu Province, ZHANG Zi-long et al. (010) used a Structure Decomposition and Analysis (SDA) model to analyse the changing trends in temporal relationship between economic growth and environmental pressures for the period of Other researchers established a dynamic coupling model for coordinated of the regional economy and the ecological system in the Jiangsu province (JIANG Hong-li and HE Jian-min, 010) and investigated coordinated of agriculture and the economy in the Shanxi Province with whilst maintaining the integrity of ecological systems (REN Zhi-yuan et al. 011). This study is focussed around the eight main cities of Shandong Peninsula-Jinan, Qingdao, Zibo, Weifang, Dongying, Yantai, Weihai and Rizhao. Using a statistical measurement model to calculate the degree of coordinated in focus areas, we put forward suggestions for viable sustainable options. The urban agglomeration of Shandong Peninsula is located in the economically developed coastal areas of North China, thereby possessing a unique advantage in being receptive to the outside world and developing an export-oriented economy. At the same time, a good domestic and international environment has provided a broad space for a spectrum of in the area. Alongside economic and urbanization, the conflict between demand for resource use and maintaining a healthy environment becomes more apparent and the negative outcomes more drastic. Clearly, the key is to protect the ecological environment whilst achieving sustainable of resources on the Shandong Peninsula. This drive is specifically important to the construction of ecologicallysensitive civilizations of the future. 1 Hydrogeological conditions of the study area The urban agglomeration of the Shandong Peninsula is the key area for of Shandong Province, and one of the important urban sites in North China. Market in Shandong s medium-sized cities is relatively sound with high competitiveness. The foundation for economic in province relies on good information communication, and with high-speed broadband network now in place for the whole region, the advantages of the regional economy and social are clear. Shandong Peninsula landforms include mountains, hills, plains, tidal flats and depressions, which form a typical estuarine delta in the Yellow River. Because of the complex terrains, the climate is warm and humid, and biological diversity is high. The marine biological resources are rich, and tourism opportunities are bountiful. The cultural landscape, natural landscape and folk tourism resources are abundant, and some have become a nation-class and even world-class tourist hot-spots. Unfortunately more than ever, the growing economy of the region has increased conflict among requirements, resources and the environment. A serious shortage of water resources, lack of land reservation resource and serious environmental pollution are all factors contributing to the problem (WANG Kui-feng et al. 014a, b). After repeated research and data analysis, the coordinated model is used in the study to analyse the degree of between resources, the environment and economic in Shandong Peninsula urban agglomeration. To measure the degree of, a quantitative description that reflects the degree of healthy and is used, determined through one or more indicators that assess the system of environment resources and economic. evaluation model of resource environment and economic for Shandong Peninsula urban agglomeration 1 65

3 Journal of Groundwater Science and Engineering Vol.4 No. No.3 Jun. Sept. 016 The coordinated of the resource environment and social economy system for the Shandong Peninsula urban agglomeration area is determined through the use of the coordinated model proposed by LIAO Chong-bin (1999) as a quantitative index. In this study, the evaluation index system of coordinated between the resource environment and the economy is based on previous research results. The frequency analysis method is used with as a keyword to search on the internet and in the China National Knowledge Infrastructure database, and also the selection principle of the index system is considered. In the end, the resource environment and economic are treated as two separate evaluation sub-systems to construct the corresponding index system. Then Analytic Hierarchy Process (AHP) is used to calculate the weight of each index, and the weighted fuzzy membership function method, geometric mean method and the linearity-weightedsum method are used to evaluate comprehensively the level of resources and economic sub-systems. The data used are derived from the Statistical Yearbook of Shandong Province, Statistical Yearbooks of Eight Cities. Finally the resource environment index and the economic index are calculated..1 Degree of model Here we define the economic index f(x) and the environmental situation index g(x). According to the definition of, coordinated refers to a state that is mutual promotion and common between the environment and economy (JIANG Hong-li et al. 010). In order to ensure the deviation of f(x) and g(y) smaller, a coefficient of variation is used to calculate the degree of model for the environment and economy. The coefficient of variation (C) is simply expressed as: whereσ is the standard deviation and x is the average value. The calculation of σ (1) and x () are performed using the following formula: 66 ( f( x) x) + ( g( y) x) σ = (1) 1 f ( x) + g( y) X = () Expressed in full, the coefficient of variation (C v ) is as follows: Cv= 1 f ( x) g( y) f( x) + g( y) The smaller the coefficient of variation (C v ) is, the better the outcome for coordinated. When C v is as small as possible, the necessary and sufficient condition is that the equation (see below) is the bigger the better. ' f( x) gy ( ) C= f( x) + gy ( ) Our study therefore defines the degree of model of the resource environment and economic about Shandong Peninsula urban agglomeration as the formula: f( x) gy ( ) C= f( x) + gy ( ) In the formula, C is the degree and K is the adjustment coefficient. To ensure K is more than, this research gives K the value of 3. Using the standard deviation formula to calculate the degree of, we can calculate the maximum benefit to both the resource environment and the economy; that is, when the sum of f(x) and g(y) are maximised. The degree of C between the two values is expressed as a figure ranging between 0 and 1. Clearly, the degree of is optimal when C is close to 1. On the contrary, a lack of between the environment and economic is indicated by a C value approaching 0.. Model for the degree of coordinated describes integration which emphasizes integrity, comprehensiveness and endogenous. Change in a single factor contributing to coordinated can therefore have relatively little affect, emphasizing the comprehensive nature of the system based on harmony and mutual promotion of multiple k

Coordination is the beneficial constraints and regulations of the common behavior. While C is an index that can describe mutual between the resource environment and the economy, it has difficulty reflecting the overall function or comprehensive environmental and economic benefits. The degree of does not describe as absolute level, but only reveals the harmonious degree of the resource environment and economy. But the degree of coordinated reflects the overall function of the resource environment and economic. To reflect and evaluate the comprehensive and coordinated level of the social economy and resource environment, a quantitative measurement model is used. This model is defined as the degree of coordinated, and is expressed as D (3): D= C Y (3) Y= α f ( x) + βg( y) (4) In the formula, D is the degree of coordinated ; C is the degree. Y (4) is the evaluation index of the resource environment and economic, wherebyα and β are weights. The contribution of each factor to the degree of coordinated are counted as equally important, therefore given the same values of 0.5. Compared with the degree model, the degree of coordinated model demonstrates greater stability and a wider application range. It can be used for quantitative evaluation and comparison of the coordinated between the resource environment and the economy for different cities or for different periods in the same city (Table 1). Furthermore, according to the relative size of resource environment evaluation index f(x) and economic evaluation index g(y), as well as the size of measure D, the type of system can be subdivided into three different levels, containing three categories and five sub-categories (Table ). When D is calculated to be , this indicates the city is one of coordinated, which can be one of either two subgroups excellent and good coordinative. When D is between , this demonstrates the city is one of excessive, either intermediate coordinated or primary coordinated. D being less than 0.30 implies a city of imbalanced. Table 1 A classification of measure based on the degree of coordinated model D, where indicates a city of imbalanced between resources, the environment and the economy, and represents cities of excellent between these factors D Good Excellent Category Imbalance In order to further discuss comprehensive of the resource environment and the economy, more detailed third levels of classification are required. In this way, the type of coordinated in the urban (or regional) resource environment and economy can be completely discriminated. Finally, according to the analysis results, this paper puts forward some suggestions for controlling the coordinated of regional resources environment and economy. When a city demonstrates a good degree of, this indicates a focus on improving the quality of the environment. A city belonging to the primary category, is one where the main task is to develop the economy based on high environmental standards, whilst improving the coordinated of the resource environment and economy at a higher level. 3 Results and discussions According to the calculation formula of the measurement model, the classification system and the standard of coordinated, measurement and classification of the degree harmony between resource use, the economy and the environment in the Shandong Peninsula urban agglomeration area can be calculated. The final evaluation results for the year 014 are given in Table 3 and illustrated in Fig. 1 and Fig

Sept. 016 Fig. Diagram of the evaluation model During the construction and analysis of the measure model, we found that the membership degree and measure value of each subsystem indicators has its urban characteristics. Overall for the Shandong Peninsula urban agglomeration, the highest measurement of was for Weihai, followed by Yantai, Qingdao, Ji nan, Weifang, Rizhao, Zibo and Dongying. We shall elaborate further the degrees of for each city. (1) The city with the highest degree of Weihai City Since the city was founded in 1987, Weihai has continuously recognised resources and environmental protection as priority contributors to economic and social. To ensure the coordinated of the economy and the resource environment, policies around ecological protection of coastal area have been established. The goal of regional sustainable in Weihai, relies primarily on focusing first on the of the marine fishing industry, export-oriented aquaculture, processing and service enterprises to cater for these industries. Secondly, Weihai aims to strengthen protection around secondary natural forest. And thirdly, 6 70 sustainable will include strengthening the protection of the ocean territory and the construction of oceanic environment. () The cities with a relatively high degree of Qingdao City and Yantai City Qingdao city has a good economic foundation and awareness around ecological health and protection, following on from long-term ecological and environmental protection and restoration projects. Yantai City has a stronger economic record than Qingdao, a higher GDP, higher potential value of mineral resources, better overall economic, and a more reasonable industrial structure and layout. The main direction of future is via strengthened environmental protection work around the key resources zone, greater marine resource and environmental protection and thirdly in improved management of water and soil erosion. (3) Cities with a moderate degree of Ji nan City, Weifang City, Rizhao City and Zibo City As an example of cities with a moderate degree of, Ji nan City is the economic and political centre of Shandong Province. It has one of

8 Journal of of Groundwater Science and Engineering Vol.4 No.3 No. Sept. Jun. 016 the higher economic aggregates, heightened urbanization levels, greater land-use ratio, higher total export-import volume and higher per capita GDP within Shandong Province. The main direction of future in this city is to construct a circular economic system such as the recycling of solid waste and a cultivated land resource ecological security system and thirdly the protection of the springs to restore Quancheng characteristics. Economic in Weifang City has made some progress. In recent years although the trending growth in pollution has been initially controlled, environmental pollution problems still exist. The carrying capacity of ecological environment is improved in Rizhao City. The strong economic foundation in Zibo City is matched by serious environmental pollution. In the future, the key direction of in cities such as these is to first readjust industrial structure for efficiency, less pollution and environmental benefits and secondly to vigorously develop an environmental protection industry. (4) The primary coordinated city Dongying City The acknowledgement of the ecological environment system in Dongying city has a short history, resources are over-exploited and the ability for self recovery is weak. According to goals of ecologically-minded economic, Dongying must invest heavily in the of an oil replacement industry, and consider the constraints of natural resources, to ensure the stability of the stock of natural resources. The main direction for future in Dongying will be to strengthen the management of inland pollution sources, to develop efficient agricultural practises and thirdly, to vigorously carry out water and soil erosion control. limiting factor for regional. Economic is not always passively subject to environmental factors. When economic activity is very high, there is commensurate level of investment in the protection of resources and the environment. In turn, this will assist in the protection and of the resource environment. A low level of economic activity is usually paired with more eagerness to develop and use resources to further develop, but such an economy is also unable to protect environmental resources. () Regional focuses on. In order to obtain the maximum economic benefits and social benefits, the relationship between environment and economy must be coordinated and a reasonable mode of must be sought to maximize the efficiency of the resource environment. (3) Due to the difficulty of data acquisition, the index of the measure of model does not completely cover all factors. Furthermore, data employed in calculations are derived from the year 014 alone. Ideally, in order to conduct dynamic and predictive research, a long-term data set is desirable. Thus, the evaluation results may be skewed and/or one-sided. Our study team aims to constantly improve in following research, to ensure that evaluation results are more scientifically robust and practical in application.
