摘　　要：以江苏省沿东陇海线地区为研究区域,利用遥感与G IS工具,研究基于模糊聚类与若干定量指标的生态功能区划方法。该方法选取了5个指标用于区划过程,首先将研究区域分成5×5km大小的空间单元,并提取各单元属性数据生成属性矩阵,利用M atlab模糊逻辑工具箱对单元进行模糊聚类。参照聚类结果与其他资料进行了生态功能区划,并根据区划结果对各分区的产业发展与生态保护提出了建议。Based on the data collected by RS and GIS from the area along eastern Longhai Railway in Jiangsu Province,the method and factors of quantitative classification in ecological function regions was developed by means of fuzzy clustering.During the process five factors were selected.Firstly the area was divided into blocks with size of 5×5km.Then the attribution of every block was obtained to generate an attribution matrix.The fuzzy logic tool Matlab was applied to cluster the blocks.As a result,the ecological ...
