7 On effects of coastal location and management policy on landuse changes in coastal zone : a case study of Golden Coastal Region in Changli County WAN G Jing2gui, SU Fen2zhen, ZHOU Cheng2hu, YAN G Xiao2mei, DU Yun2yan, CH EN Xiu2fa ( Institute of Geographic Sciences and Natural Resources Research, CAS, Beijing , China) Abstract :The protection and rational use of coastal resources are keys to sustainable devel2 op ment in coastal zones, which are influenced by many nat ural and social factors such as coastal locatio n and management policies1 To realize sustainable develop ment of coastal zones, t he influence mechanism of impact factors on landuse changes must be st udied and rational policies are made based on the study1 To learn the effect s of coastal location and management policies of coastal zone on t heir landuse changes, as a case st udy, t he pattern of landuse changes f rom 1985 to 2000 in Golden Coastal Region of Changli county, Hebei p rovince was st udied in t his paper1 The landuse change in near2coastal and far2coastal zones shows t hat coastal location has great effect on landuse changes in coastal zone, and landuse change degree of near2coastal zone is greater than t hat of far2coastal zone and t heir main change types are different - t he main change types in near2coastal zone are t he con2 versio ns of beaches, lagoo ns, sand dunes, grasslands and farmlands into fishpo nds and sand dunes into grasslands and forestlands, while t he main change t ypes of far2coastal zo ne are the conversions of farmlands into rural residential areas and sand dunes, and saline2al2 kali lands into farmlands, fishpo nds and grasslands1 The co mpariso n of landuse changes between protected area and develop ment area, which are bot h in near2coastal zone, was made and t he result s prove that management policies of coastal zones have great effect s on landuse changes, too1 Landuse change degree in protected area is smaller than that of de2 velop ment area, and t he main change types in protected area are sand dunes into forest2 lands and grasslands and lagoon into fishponds, while t he main change types in develop2 ment area are affected by different develop ment policies, t he main change types of tourist area are forest into lands for to urism and recreatio n p urpo se and residential areas, and t hose of fishery cult ure area are grasslands and beaches into fishponds1 The analysis also shows t hat t he protected area has played it s positive roles in p rotection of lagoons, sand dunes and forest s after it s construction, but t he area of t he Qilihai lagoon is about 315km 2 now because of cultured fishponds around the lagoon before t he construction of protected area, therefore we must protect t he lagoon actively and forbid it s continuous cult uring and ret urn t he fishponds back to t he lagoon1 Key words :Golden Coast in Changli ; landuse change ; coastal locatio n ; management policy of coastal zone
