Abstract:

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.

Key words: coastal area of Yancheng City, location choice, natural ecological resistance, economic gravitation, spatial analysis technology
