我国为了防治土壤侵蚀,深入研究并采取了二十多种不同的防蚀方法,说明这些方法效果的基本数据列在表1里.这些方法使我们能够全部或部分的拦阻径流,使地表径流转变为地下径流,分散并减少急流来保护土壤不受侵蚀,从而减轻或消除在播种农作物的情况下对不同坡度土壤的破坏. In order to prevent and control soil erosion, our country has studied and adopted more than 20 different anticorrosive methods, and the basic data showing the effects of these methods are listed in Table 1. These methods enable us to completely or partially block runoff and transform surface runoff For underground runoff, scatter and reduce rapids to protect the soil from erosion, thereby reducing or eliminating damage to soils with different slopes when crops are sown.
