How to prevent soil from being washed away

Academically known as preventing soil erosion, the main ways are:

1. Strictly control any form of development and construction activities. If construction is really necessary under special circumstances, the soil and water conservation scheme should be fully demonstrated and effective measures should be taken to prevent the occurrence and development of soil erosion.

2. Establish ecological compensation mechanism for soil and water conservation. Adhere to the principle of "whoever occupies and destroys, whoever recovers and compensates", and 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 technology. We will build high-standard soil and water conservation facilities and high-and stable-yield farmland, and at the same time change unreasonable farming systems such as sloping farmland and steep slope land reclamation, increase the amount of organic fertilizer, rationally rotate crops, and return straw to the fields to improve soil erosion and erosion resistance.

Extended data:

Soil erosion is the main form of land degradation and ecological deterioration, and it is also a concentrated reflection of the degree of land degradation and ecological deterioration. Its impact on economic and social development is multifaceted, comprehensive and far-reaching, and even irreversible.

Soil erosion leads to land degradation and cultivated land destruction, which makes people lose their survival foundation and threatens national food security. The per capita arable land area in China is far below the world average, and the contradiction between man and land is prominent, which is aggravated by serious soil erosion. The average cultivated land lost by soil erosion in China every year is about 6,543,800 mu. A considerable proportion of farmland in the rocky mountainous areas in the north, karst areas in the southwest and the upper reaches of the Yangtze River has lost topsoil and exposed parent rocks, completely losing agricultural production capacity.
