Nature of Soil and Water Conservation Is an Economic Action

摘要

With our long history of agricultural development, soil and water conservation appeared, which was a great cause in China. During the long time, Chinese people had accumulated a lot of practical experiences about soil and water conservation and created lots of practical technology. Now it develops better. But our developments of soil and water conservation theories are not satisfied. Some theories lagging behind practices can't have a positive effect on practices, while, hinder the development of practices. From most important aspects, some basic theories of soil and water conservation, for example, the category of soil erosion, the definition of calamity nature, the accurate assessment of calamity on soil erosion, the basic approaches of soil and water conservation and other big questions, can't be solved well and they need to discuss more deeply.
