People-oriented, innovative ideas for controlling soil desertification

First, encourage relevant departments to increase the construction of basic farmland and grassland in existing sand areas and increase the output per unit area. Support the agricultural sector to propose grassland construction, banning grazing or increasing farmland construction.

Second, the implementation of closing hillsides (sand) for afforestation should solve the energy and fuel problems in rural areas. Relevant state departments are conducting pilot research on rural energy construction projects, and biogas digesters can be developed in southern China. The construction of biogas digesters is four in one, with an average of more than 4,000 yuan per pool, and the state subsidizes about 1000 yuan per household, thus avoiding firewood burning. At the same time, the northern region can develop wind power generation and solar energy utilization.

Third, individual areas can migrate ecologically to achieve the purpose of closing hillsides for greening. The alpine, alpine and remote areas which are not suitable for production and life, such as fragile ecology, inconvenient transportation and serious endemic diseases, should be moved in an organized and planned way. The government demarcates basic farmland and subsidizes housing construction, and the state subsidizes about 25,000 per household. Grassroots units are allowed to concentrate limited funds, including closing hillsides for afforestation, poverty alleviation, grain subsidies for returning farmland to forests, and closing hillsides for greening by ecological immigrants.

Fourth, encourage the masses to keep the basic grain ration fields, increase investment, increase the output per unit area, and lay the foundation for other desertified cultivated land to increase returning farmland to forests.

Fifth, the national ecological goal should be organically combined with the increase of people's income and the development of regional economy, and forestry and ecological construction must find this combination point. For a long time, the purpose of afforestation work is not strong, and this view must be changed. Afforestation should be linked with the macro-ecological goal of China, and combined with increasing people's income, increasing enterprise benefits and increasing government taxes. Therefore, the ecological construction should first choose varieties and models, and develop some tree species and grass species suitable for local ecological and economic benefits. Seabuckthorn, Caragana korshinskii, Haloxylon ammodendron (inoculated with Dayun), Glycyrrhiza uralensis and other varieties and some intercropping patterns have achieved good results. In Siziwangqi, Wumeng, Inner Mongolia, people used to grow grain on sandy farmland, and the annual net income per hectare was less than 150 yuan. Moreover, due to the harm of sandstorms, it had to be replayed several times. Now Caragana korshinskii is planted on the sandy land, and the net income per hectare reaches10.5 million yuan. The forest medicine model and forest fruit model also have good effects. The model of "company+base+farmer" is very promising. As long as a county can select one or two projects correctly, under the pull of the whole industry, ecological construction can make a leap and people's economic income can be greatly improved. At present, the people in the sand area are still very poor, and it is far from enough to rely on one household to carry out ecological construction. It must be developed on a large scale under the guidance of the government, and finally realize the organic combination of ecological construction and people's income increase.
