| 摘 要： | 运用GIS软件的数据库管理功能和栅格数据空间分析功能,根据修正的通用土壤流失方程(RUSLE)的形式,读取数据库文件,生成该模型的各因子专题图。然后借助GIS软件的地图代数运算,将各因子连乘,得到土壤侵蚀量栅格图,并对其进行分类,获得1998年和2004年两期的土壤侵蚀等级分布图。进而对这两期的土壤侵蚀量进行统计和变化分析。再将得到的土壤侵蚀图与土地利用图叠加,最终获得不同土地利用类型下的土壤侵蚀量,据此对土壤侵蚀与土地利用类型之间的关系进行了分析,以期为水土流失的防治和保护规划方案的制定提供科学依据。

| Abstract: | Integrating geographical information system (GIS) with the change of soil erosion, we adopted RUSLE and map algebra operation of the GIS software, and succeeded in producing a digital map of factors. We proceeded to classify it and got Raster Map Layers for soil erosion and maps of grade distribution of 1998 and 2004. Then we counted soil erosion and analyzed the change of it. Overlapping the two maps of the soil erosion and land-use, we gained the quantitative report of soil erosion in different land-use conditions. By analyzing the relation between soil erosion and land-use style, we obtained some scientific bases for the prevention of soil erosion and the making of protective plans. |
