控制坡地水力侵蚀危害的管理措施
- Title:
- Measures of Management for Controlling Water Erosion on Slopes
- Keywords:
- water erosion; measures of management; slope land
- 分类号:
- S157.1
- 摘要:
- 根据坡面水力侵蚀由降雨击溅力和径流侵蚀力作用于坡面土壤，从而引起土壤颗粒的剪切破坏分离，被径流携带引起流失的作用机理，从植被覆盖、人工覆盖、消减径流量、减小径流流速、增强土壤抗分散、抗剪切能力等方面入手，采用适宜的生物、工程、耕作及化工产品综合措施，达到防止或减轻坡面侵蚀，保护土地生产力之目的。
- Abstract:
- Based on the principle of soil particles sheared and damaged by rainfall impact and runoff on slopes,effects of vegetation cover and artificial mulch on increasing the speed of runoff,increasing soil abilities to resist dispersion and shear stress were discussed.A comprehensive measure of tree,grass,project of soil and water conservation tillage and chemical products were adopted so as to prevent or relief erosion and protect productivity of slope land.
