为及时掌握地形复杂的拜城县土壤侵蚀情况,本文综合运用遥感影像、土地利用数据、地形图(DEM)和植被覆盖度指数,构建了基于RS和GIS的拜城县土壤侵蚀分类分级监测方法,并借助ENVI和Arc GIS软件,分析了该区2000年至2013年的土壤侵蚀动态变化情况。结果表明:拜城县土壤侵蚀以微度和中度为主,13年间土地好转面积远高于退化面积。2000—2013年拜城县土壤侵蚀情况总体在改善。
In order to grasp the situation of soil erosion in Baicheng County with complex terrains in a timely manner, this paper constructs a classification monitoring method of soil erosion in Baicheng County based on RS and GIS by comprehensively using remote sensing images, land use data, topographic maps (DEM) and vegetation coverage index , And analyzed the dynamic changes of soil erosion from 2000 to 2013 with ENVI and ArcGIS software. The results show that the soil erosion in Baicheng County is dominated by degree of micro and moderate, and the area of land improvement is much higher than that of degraded area in 13 years. Soil erosion in Baicheng County during 2000-2013 is generally improving.
