Method for harnessing desert by using honeycomb type water accumulation holes

Abstract

The invention provides a method for harnessing a desert by using honeycomb type water accumulation holes. The method comprises the following steps that (1) excavation of the water accumulation holes,wherein staggered sand pits are excavated on the surface layer of the desert to form the honeycomb type continuous-piece water accumulation holes; (2) preparation of slurry, wherein desert yellow sand, cement and gypsum powder are taken as raw materials and are stirred into the slurry after being mixed with water; (3) paving of the slurry, wherein the slurry is laid on the surface layer of the desert containing the water accumulation hole wall; (4) slurry breaking, wherein the laid slurry is cut, massive or spherical material blocks of which the size is 3-10 cm and which are staggered are formed on the surface layer of the desert containing the water accumulation hole wall, and vegetation growth tanks are formed between gaps between the material blocks; (5) planting, wherein woody plants suitable for growing in the desert are planted in the water accumulation holes. The method for harnessing the desert by using honeycomb type water accumulation holes has the advantages that the desertharnessing efficiency is high, the method can be implemented in a large area in the edge area of the desert; the harnessing cost is low, the raw materials are cheap and easy to obtain, and it can be achieved that the materials are obtained from local sources; the sand fixation can be effectively achieved, and the formation of quicksand is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of desertification control, and relates to a method for controlling deserts by using honeycomb water-collecting caves. Background technique [0002] The phenomenon of desertification has seriously threatened the living environment of human beings and the development of social economy. At present, the desertification area in my country has reached 2.62 million square kilometers, accounting for 27% of the country's land area. At the same time, my country is also one of the countries in the world with large desert area, wide distribution and serious desertification hazards. Desertification not only causes the imbalance of the ecosystem, but also shrinks the area of ​​arable land, which has a serious impact on my country's industrial and agricultural production and people's lives. The desert and desertified land in the arid region of Northwest my country have become one of the main sources of sandstorms in Chin...
