基于GIS的土壤侵蚀与土地利用关系分析

Analysis of the Relationship Between Soil Erosion and Land Use Based on GIS

土壤侵蚀分布与土地利用类型分布之间存在密切关系。以我国水蚀区广东惠东区为例 ,以 TM影像为主要数据源 ,在 GIS环境下 ,进行土壤侵蚀与土地利用类型的矢量分析 ,通过 SPSS软件包的统计分析 ,得出土地利用类型与土壤侵蚀的分布相关关系 ,其程度依次为林地、耕地、草地、城镇。

There is a close relationship between soil erosion and land use.Take Huidong district, in Guangdong Province for an example,TM image is used as the main datum resource. With GIS,the analysis of soil erosion and land use is made.The datum gotten in GIS is put into SPSS and a conclusion is drawn from results, the order of relationship between soil erosion and land use is as follows: woodland,cultivated land,grass land,township. Therefore based on this,the relationship between soil erosion and land use type is analyzed in regions.
