该文依据作者20多年对水土保持科研工作的实践,提出了进行水土保持科研的基本思路是:一定强度的降雨降至无覆盖的坡地地表土壤上,引起水土流失。通过建造植被、水土保持耕作、水土保持工程措施,或通过上述措施的复合组装,或通过复合措施的优化配置,使降雨不能直接达到坡地地表土壤上;或使降雨降至平地,不足引起水土流失,达到保持水土的目的。同时依据这一基本思路,提出了进行水土保持科学研究应采取的主要措施,主要内容和技术路线。
Based on the author ’s practice of scientific research work on soil and water conservation for more than 20 years, this paper puts forward the basic idea of scientific research on soil and water conservation that a certain intensity of rainfall is reduced to uncovered surface soil on sloping land, causing water and soil loss. Through the construction of vegetation, soil and water conservation farming, soil and water conservation measures, or through the combination of the above measures, or through the combination of the optimal allocation of measures so that rainfall can not directly reach the topsoil slope; or to rainfall to the ground, insufficient to cause soil erosion , To maintain the purpose of soil and water. At the same time, based on this basic idea, the author put forward the main measures, the main content and the technical route that should be taken in the scientific research of soil and water conservation.
