利用数字高程模型(DEM)实现坡耕地数据的自动提取和侵蚀状况调查,并与实地勘察及相关研究结果进行对比.结果表明,三峡库区平行岭谷地貌、出露的侏罗纪紫色泥(页)岩和砂岩互层结构及人为活动是小尺度坡耕地地形的关键控制因素.

By using DEM, slope information was extracted automatically and soil erosion situation was investigated. Then compared with field survey and related research. The results showed that parallel ridge valley in Three Gorges Reservoir Area, the interbedded structures formed by Jurassic purple clay (page) rocks and human activities are the key controlling factors of small-scale sloping terrain.
