| 摘 要： | 土壤侵蚀造成一系列的危害,己成为威胁生态安全的头号问题。采用中巴地球资源卫星02星的遥感资料,选取适合的波段,结合实地考察收集的信息,采用了第二次全国土壤侵蚀遥感调查中的多因素综合法,提取了对土壤侵蚀起主导作用的植被覆盖度、土地利用类型,借助数字高程模型提取地形坡度,依据《土壤侵蚀分类分级标准》建立了土壤侵蚀分析模型,将上述几个因子进行交叉分析,得到了研究区的不同土壤侵蚀强度的分布、面积情况,为中巴地球资源卫星在生态环境监测中的应用提供了经验。

| Abstract: | A series of hazards have been caused by soil erosion, which has become the most serious environment problem in China. In this research, two main factors in erosion, vegetation cover and land-use type were obtained from CBERS data. Land slope was obtained from digital elevation model. Soil erosion analysis model was established according to the Classification and Gradation Criterion of Soil Erosion, soil erosion intensity and distribution were gained from this model. Enlarge the application area ot CBERS on ecological environment monitoring. |

| Keywords: | CBERS soil erosion monitoring remote sensing geography information system spatial model |
