摘要： 土地资源是一个复杂的系统,这个系统是由气候、水文、地貌、土壤、植被等许多因子组成的,它们不仅在空间上互相联系、互相制约,而且还不断地进行着物质与能量的交换过程。因此要对这样复杂的土地资源进行分类与评价,仅仅停留在定性描述阶段,那是远远不够的。为此,不少地学工作者探求用指数法、加权平均法、聚类法等等来解决有关问题。由于土地资源评价等级之间的界限常常是不分明的,所以用Fuzzy数学方法处理更为合适。下面我们以江苏省太湖地区土地资源的分类与评价工作为例,说明Fuzzy聚类分析方法的具体应用。

Abstract: In this paper a method of classification cvalution of different land units in the light of land quality is introduced on the basis of fuzzy clustering analysis. It is put forward here that according to the regional features of geography and research subject, suitable evalution elements and indexes for the method should be selected, and then marks are given on the basis of synthetic analysis to form a group of fuzzy Subsets, After fuzzy clustering analysis, a comparison is made between its results and those forms—ordinary methods of classification evalution.
