Understanding of countermeasures for sand prevention and control in Soviet reclamation area

The purpose is to protect the existing vegetation, strengthen the construction of forest and grass, and solve the problem of population and livestock quantity at the same time; Give full play to the self-repair function of the ecosystem.

1. To prevent and control desertification, it is necessary to protect existing vegetation and strengthen forest and grass construction. At the same time, it is necessary to solve the problems of population, livestock and stoves, protect forest and grass vegetation in sandy areas, rationally allocate trees, shrubs and grass through afforestation, expand the proportion of forest and grass, and establish a multi-forest, multi-tree and multi-level three-dimensional protection system.

2. While artificially controlling desertification, we should give full play to the self-repair function of the ecosystem, increase the intensity of closure and protection, and enhance the ability of ecological natural restoration. Because aerial seeding has the characteristics of high speed, less labor, low cost and good effect, it can help to restore vegetation in remote deserts and barren hills with vast land and sparse population and inconvenient transportation, so aerial seeding can be used to plant vegetation.

3. Desertification areas can carry out a lasting ecological revolution and accelerate the reversal of desertification process. The key is to rationally allocate water resources and ensure ecological water use. Usually, the unreasonable allocation of water resources is the direct cause of shortening rivers, shrinking lakes or even drying up, lowering groundwater level and land desertification in northwest China.

4. Strictly implement the family planning policy, control the population growth rate, prevent the population from growing too fast, continuously improve the quality of the population, carry out environmental awareness publicity and education lectures, and improve people's ideological level. Care for the environment at ordinary times, consciously participate in the transformation and construction of the environment, and form a good social atmosphere.

5. The state needs to implement the ecological migration policy in areas where desertification is very serious, grasslands and cultivated land are almost completely abandoned, and the harsh natural environment is no longer suitable for human survival.

6. 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, change the backward situation of raising livestock naturally and in houses, reduce the damage to grassland, accelerate the cultivation of excellent livestock breeds, and optimize the structure of livestock breeds.

7. While doing a good job in international implementation, we should strengthen international exchanges and cooperation in combating desertification, and strive for funds and foreign aid to combat desertification.

8. Optimize the energy structure of agricultural and pastoral areas, vigorously advocate and encourage people to use unconventional energy sources, such as wind energy, light energy, biogas and other energy sources, in order to reduce the damage to forests, grasslands and other resources.
