摘要
在黄土高原沟壑区的淳化县泥河沟流域 ,以常规耕作的直线坡为对照 ,对等高耕作、人工掏挖、人工锄耕的蓄水保土情况进行了人工降雨试验 ,结果表明 ,各种耕作措施均可提高土壤稳定入渗率、延长产流时间、降低坡面径流流速及减少坡面产流量、降低侵蚀模数等 。
It conducts artificial rainfall tests on the soil and water conservation of contour farming, manual excavation, hoeing and ploughing in Nihegou Watershed of Chunhua County in the gullied loess plateaus by taking straight-line slopes of conventional farming as check. The outcomes show that all measures of cultivation can increase the stable infiltration rate of soil, extend contributing time and reduce runoff velocity and runoff yield of slope surface and erosion modulus, of which, the function of contour farming is the most remarkable.
