| 摘 要： | 以GIS、RS和修正的土壤流失方程(RUSLE)为基础,结合遥感影像解译数据、地形图及降雨资料等,对麻地沟的土壤侵蚀进行了定量分析,并根据土壤侵蚀定量计算结果,结合景观生态学的方法,分析土壤侵蚀引起生态环境效应的因子,包括植被指数和景观指数等,对麻地沟地区的生态环境效应进行了分析。结果表明:研究区土壤侵蚀状况正在逐步好转,坡耕地和坡荒地是发生土壤侵蚀面积相对较高的两种土地利用类型,在保证当地居民所需坡耕地的情况下,修造梯田和植树造林是控制土壤侵蚀最有效的方式。

| Abstract: | Based on GIS and RS software and the revised universal soil loss equation(RUSLE),a quantitative study is made of the soil erosion of the Madigou area,in combination with RS data,topographic maps and rainfall data and so on.The eco-environment effect factors caused by soil erosion,including vegetation index and landscape index,etc,are also analyzed.Based on soil erosion results and combining the method of landscape ecology,the eco-environment effect of the Madigou area is analyzed.The results show that the s... |
