我国土壤侵蚀面积达492万km2,占国土总面积的51.2%,已严重影响和制约国民经济的发展和社会的安定。文章仅对牧区草地土壤风蚀和水蚀加以分析,同时对草地开垦与风蚀、水蚀的关系进行了讨论,认识到不合理的草地利用活动,是目前加速草地土壤侵蚀的重要问题之一,也是破坏生态环境平衡的重要问题。因此,研究土壤侵蚀产生的原因和发展规律,了解影响土壤侵蚀的最为关键因子,将对防止土壤侵蚀的危害具有重要意义。
The area of soil erosion in China has reached 4.92 million km2, accounting for 51.2% of the total land area, which has seriously affected and restricted the development of national economy and social stability. The paper only analyzes the pasture grassland wind erosion and water erosion, and discusses the relationship between grassland reclamation and wind erosion and water erosion. Realizing that irrational use of grassland is one of the most important problems in accelerating grassland erosion. The important issue of environmental balance. Therefore, to study the causes and development of soil erosion and understand the most critical factors affecting soil erosion will be of great significance to prevent the harm of soil erosion.
