Academically known as the prevention of soil erosion, the main ways taken are:
1, strict control of any form of development and construction activities, there are special circumstances must be constructed, should be fully carried out soil and water conservation program demonstration, and effectively take soil and water erosion prevention and control measures, to prevent soil and water erosion from occurring and developing.
2, the establishment of soil and water conservation ecological compensation mechanism. Adhere to the principle of "who occupies and destroys, who restores and compensates", establish and improve the compensation system for soil and water conservation.
3, scientific planning and rational use of land, comprehensive promotion of soil and water conservation farming techniques. Construction of high-standard soil and water conservation facilities and high-yield farmland, while changing the slope farming, steep slopes and other irrational farming system, increase the application of organic fertilizers, reasonable crop rotation, straw return to the field, and improve soil erosion resistance, resistance to washing ability.
Expanded Information:
Water and soil erosion is both the main form of land degradation and ecological deterioration, as well as a centralized reflection of the degree of land degradation and ecological deterioration, the impact on economic and social development is multifaceted, global and far-reaching, and even irreversible.
Water and soil erosion leads to land degradation, the destruction of arable land, so that people lose the basis for survival, threatening national food security. China's per capita possession of arable land area is far below the world average level, the contradiction between man and land is prominent, serious soil erosion and exacerbate this contradiction. The average annual loss of arable land due to soil erosion in China is about 1 million mu. Northern soil and rocky mountainous areas, southwestern karst areas and the upper reaches of the Yangtze River and other places have a considerable proportion of farmland cultivation layer of soil has been lost, the parent bedrock is exposed, a complete loss of agricultural production capacity.
