在对地域主体功能区划的理论依据与原则等进行深入分析的基础上,提出通过生态敏感性等级分区与经济社会发展综合潜力等级分区的空间叠置与地域聚类分析,进行地域主体功能区划的理论方法。并以江苏省新沂市为案例,进行地域主体功能区划实证研究,验证了所提出的地域主体功能区划理论方法的可行性。

The major function regionalization is one of the territorial division methods with specific function,which is based on the factors of natural environment,the level of social development,the features of ecological system,and the spation diversity of human activities.For the ends of constructing rational and spatial arrangement according with the major function of units,the major function regionalization would guide the factors circulating rationally,and formulate the distribution,in which population,resources,environment and economy develop coordinately,with clear major function and aims,and canonical exploitation order.Based on studying progress of geographic regionalization,the dominant ideas,rationale and principles of the major function regionalization preliminarily,this paper give the major function regionalization methods,which is based on the grade subregion of eco-environmental sensitivity and the potentialities of development of economy and society,by spatial overlap analysis within GIS.By a case of Xinyi City of Jiangsu Province,this paper has made the empirical analysis with this method,and verified the feasibility of it.
