基于模糊聚类的区域主体功能分区研究--以江苏省为例

主体功能区是对区域土地的自然、经济和生态属性进行综合鉴定,并加以分类的过程;模糊聚类分析是根据研究对象本身的属性来构造模糊矩阵,并在此基础上根据一定的隶属度来确定聚类关系的方法.结合模糊聚类分析的特点,以区域土地利用为研究对象,将模糊聚类的思想引入主体功能区中,建立了基于"社会-经济-生态"为一体的指标体系.然后以江苏省为例,将其划分为优化开发区、重点开发区、限制开发区.结果表明,用模糊聚类分区法对区域土地资源主体功能区划分,能够取得较好地分类结果,对今后区域更好的协调发展有一定的推动作用.

Regional Land Main2function Division Based on Fuzzy Cluster Analysis -A Case Study of Jiangsu Province

The main-function regionalization is a course of judging the properties of nature and economy and then classifying them. Fuzzy clustering method is the optimization technology that may be used to create fuzzy matrix and ensure clustering relation by subjection according to the properties. The idea of fuzzy clustering is introduced in the land classification based on the regional landuse and nature economic society indexes. By taking Jiangsu Province for an example, the main functions of the region are divided into priority development zone, key development zone, and rest ricted development. Result from the study shows that the method is practical and effective.
