| 摘 要： | 南小河沟流域是属于黄土高原沟壑区的一条典型小流域，对该流域土壤侵蚀情况的调查和收集的数据，需要建立数据库对其进行有效管理。通过GIS平台，利用高分辨率卫星影像及1∶10 000地形图，对该流域的土地利用、植被覆盖状况及坡度组成等情况进行调查，建立土壤侵蚀数据库，为流域的进一步治理和管理提供本底数据。

| Abstract: | Nanxiaohegou basin is a typical small basin in loess gully plateau region.A database of investigation for soil erosion situation in the watershed and collected data should be established to manage it effectively.Based on the GIS technique，database for the soil erosion in Nanxiaohegou basin was established by studying land utilization，vegetation coverage and slope information of area.Database could provide basis for harnessing soil erosion in Nanxiaohegou basin. |
