[目的]此项对比试验是为了探求不同的土壤类型和植被种植组合前提下土壤流失效应,为后续在该地区的生态恢复工程提供实验依据。[方法]利用微景观结构对水分的运动影响原理和不同景观因素在空间上的不同组合,设计了3个不同实验地的多种土壤、作物和立地条件组合。[结果]不同土壤、坡度、种植品种极大影响水土流失量。草地极大地增加了水入渗,减少水土流失;豆科作物比禾本科作物苔麸在减少水土流失有更佳表现。[结论]分析试验数据,为埃塞俄比亚阿姆哈拉州减少水土流失,合理农业种植与保护模式提供科学参考。
[Objective] The comparative experiment is to explore the soil loss effect under different soil types and vegetation planting combinations, and provide the experimental basis for the subsequent ecological restoration project in this area. [Method] Based on the principle of micro-landscape structure’s influence on water movement and different spatial combinations of different landscape factors, a variety of combinations of soil, crop and site conditions were designed in three different experimental sites. [Result] Different soil, slope and planting varieties greatly affected soil erosion amount. Grasslands greatly increase water infiltration and reduce soil erosion; leguminous crops have better performance than gramineous bran bran in reducing soil and water loss. [Conclusion] The experimental data were analyzed to provide a scientific reference for the reduction of soil and water loss, rational agricultural planting and protection mode in Amhara prefecture of Ethiopia.
