摘要：
以黄前流域为研究对象，以减少水土流失为目的，运用3S软件和水土保持相关理论，通过对2008年ALOS影像解译，研究黄前流域内土地利用、坡度、高程和植被盖度因子对土壤侵蚀的影响。结果表明：流域内土壤侵蚀强度类型以轻度侵蚀和中度侵蚀为主；侵蚀主要发生在坡度为5°~35°、高程200~800 m、植被盖度45%~75%的林地和园地。水土流失区域主要发生在人类活动剧烈的园地，说明人类活动对流域的土壤侵蚀有很大的影响。

Abstract:
In order to alleviate soil and water erosion, influences of land use, slope, altitude and coverage to soil erosion were investigated and analyzed at the base of techniques of 3S and theories on soil and water conservation through interpreting ALOS image of 2008 in Huangqian valley. In the studied valley，mild soil erosion and moderate soil erosion were the main erosion types. And the erosion mainly happened in forest land and garden plots where the slope was 5°~35°, the altitude was 200~800 meters and the vegetation coverage was 45%~75%. Most soil and water erosion distributed in garden plots of intense human activities, which proved that human activities had large influence on soil erosion of valley.
