盐城市沿海的适宜开发空间选择研究

开发空间选择通过辨识适宜开发空间，使得工业发展、城市建设活动尽可能地配置在弱自然生态阻力、强经济引力的空间，实现区域生态、经济效益的最大化。借鉴以往研究，结合案例区特点，建立指标体系，基于乡镇单元，运用GIS工具综合分析盐城市域自然生态阻力和经济引力的空间分异特征，运用矩阵列联分类方法划分空间开发适宜类型，并根据适宜开发空间的地域特点将其分为城市区域和临港区域。研究认为，盐城沿海的适宜开发空间主要分布于204国道沿线的县市城区、部分临近乡镇及沿海陈家港、滨海港、海通镇等地区；临海部分乡镇凭借其资源潜力宜作为临港区域，是未来的主要产业空间载体；其它地区应定位于城市化空间，未来建设用地指标应优先向这些区域投放，引导人口、产业向这些地区的集聚。

EVALUATION ON THE SUITABLE DEVELOPMENT LOCATION IN COASTAL AREA OF YANCHENG CITY, JIANGSU PROVINCE

To select an area for social and economical development,we need to address the environmental impact,and to achieve low ecological effect and high economical potential.This paper sets up the index system by combining previous study results with characteristics of studied areas,and on the basis of the cell of town,GIS method in order to analyze the spatial disparities of the natural ecological resistance and the economic attraction that have effects on the location choice of economic activities.Furthermore,the studied area was divided into different suitable types through the matrixes,the rows and lines of which are made up of natural ecological resistance class and economic attraction class,to identify city areas and port districts in the suitable development area on the basis of territory features.Finally,this study shows that most of the suitable development area in coastal areas of Yancheng includes areas along the country road of Number 204 and some towns close to the sea such as Binhaigang,Chenjiagang,and Haitong towns,and towns near to sea should be the main spatial carrier for industrialization in the future.The other areas should be the suitable space for the urbanization,and construction land distributed to those areas should have an increase in the future to accelerate the development.
