What are the prevention and control measures of land desertification?

1. Protect existing vegetation and strengthen forest and grass construction. While strengthening management, we should effectively solve the problems of population, livestock and stoves, and strictly protect the forest and grass vegetation in the sand area. Through afforestation, rational allocation of trees, shrubs and grasses, a multi-forest, multi-tree and multi-level three-dimensional protection system will be constructed to expand the proportion of forests and grasses. While doing a good job in manual management, we should give full play to the self-repair function of the ecosystem, increase the intensity of enclosure and protection, and promote the natural restoration of ecology. Because aerial seeding has the characteristics of high speed, less labor, low cost and good effect, it is of greater significance to restore vegetation in remote and barren areas with sparse population, inconvenient transportation and barren hills.

2. Carry out a lasting ecological revolution in the desertification area to accelerate the reversal of the desertification process. The key is to rationally allocate water resources and ensure ecological water use. For example, the unreasonable allocation system of water resources is the direct cause of the shortening of rivers, the shrinking or even drying up of lakes, the decline of groundwater level and land desertification in northwest China.

3. Strictly implement the family planning policy, control the excessive population growth, and constantly improve the quality of the population. Improve the ideological level of the whole nation through publicity and education on environmental awareness. Care and care for the environment, consciously participate in the transformation and construction of the environment, and form the fashion of the whole society. At the same time, in areas where local desertification is very serious, grasslands and cultivated land are almost completely abandoned, and the harsh natural environment is no longer suitable for human survival, the state should carry out ecological migration in a planned way.

4, reverse the backward situation of relying on the sky to raise livestock and reduce the damage to grassland. It is necessary to implement the grassland contract responsibility system, stipulate a reasonable livestock carrying capacity, vigorously promote enclosure and rotational grazing, vigorously develop artificial grassland or artificially improve grassland, and raise livestock. Accelerate the cultivation of excellent livestock and poultry breeds and optimize the structure of livestock and poultry breeds.
