土地综合承载力指标体系设计及评价——中国东部沿海地区案例研究

Design and evaluation on the indicator system of land comprehensive carrying capacity

论文在对土地承载力进行简要回顾的基础上 ,构建了一套适合于东部沿海地区的区域土地承载力综合评价指标体系 ,并运用均方差权数决策法 ,将该区土地承载力划分为3种类型区 ,即 :低承载力区、中等承载力区、高承载力区 ,分别代表土地承载力演替从低层次的均衡发展阶段较高层次的不均衡发展阶段高层次的系统协调均衡发展阶段。

In recent years,eastern China has made great progress in economy. But with its rapid development,man land conflicts have become more and more serious. This paper,based on the review land carrying capacity,constructs a set of indicator system for comprehensive evaluation of regional land carrying capacity that can be adapted to eastern China. More over,by the use of a certain mathematical method,we can divide this region into three types according to the carrying capacity: the lower level carrying capacity subregion;the mid level carrying capacity subregion;and the higher level carrying capacity subregion. All these types stand for three steps of succession to the land carrying capacity,that is,from the harmonious step at lower level,imbalance step at middle level to the harmonious step of the advanced system.
