一、土壤侵蚀学必须要有自己 的分类系统和方法 正确划分土壤侵蚀类型不仅是土壤侵蚀理论研究的需要,也是发展国民经济的需要。 我国是个文明的农业古国,对治水治土、合理利用土地有着悠久的历史。建国以来特别是近几年来,在党的关怀下,水土保持工作规模空前。土壤侵蚀及其防治的理论研究和实践经验,不断丰富和发展了土壤侵蚀学。但因我国地域辽阔,各地自然条件差异大,造成土壤侵蚀类型多样,加之土 First, soil erosion science must have its own classification system and method Correct classification of soil erosion types is not only the need of theoretical research of soil erosion, but also the need of developing national economy. Our country is a civilized ancient country of agriculture, which has a long history of governing the land by water and using the land rationally. Since the founding of the People’s Republic of China, especially in recent years, under the care of the party, soil and water conservation work is unprecedented in scale.
