Desert-governance greening system capable of forming desert underground reservoir

Abstract

The invention discloses a desert-governance greening system capable of forming a desert underground reservoir. The desert-governance greening system comprises a leakage-proof box, a water collection pipe, a water diversion membrane and a protecting piling wall. The leakage-proof box is buried in an accommodating pit below a desert area to be greened, wherein a vegetation material is arranged on the desert area to be greened. The protecting piling wall is arranged on one side of the desert area to be greened. The water collection pipe is inserted into the leakage-proof box along a water inlet. A plurality of water inlet holes are formed in the wall of the water collection pipe. In this way, the water diversion membrane is used for stopping water from seeping into a deeper layer and enabling the water to be diverted into the leakage-proof box for storage, and therefore the water can be pumped out through the water collection pipe for use when the water needs to be used. Meanwhile, the area over the leakage-proof box is covered with the vegetation material, so that the water is not prone to evaporation and loss, and a better water retention effect can be achieved; the protecting piling wall is utilized in cooperation for resisting sand storms and slowing down desert migration; the desert underground reservoir formed in this way can be used for effective desert-governance greening; moreover, the desert-governance greening system capable of forming the desert underground reservoir is simple in structure, easy to construct, low in cost and worth popularizing and using.

Description

technical field [0001] The invention relates to the technology in the field of greening construction, in particular to a system for forming desert underground reservoirs to control desert greening. Background technique [0002] my country is also a country with serious land desertification. The area of ​​desert and desertification has expanded from 667,000 square kilometers in 1949 to 1.3 million square kilometers in 1985, accounting for about 13.6% of the total land area. According to the announcement of China's State Forestry Administration on June 17, 2006, China's desertified land has reached 1,739,700 square kilometers, accounting for more than 18% of the country's land area, and affecting 30 first-level administrative regions (provinces, autonomous regions, and municipalities) across the country. Sandy land is also growing at a rate of 60 square kilometers every year. [0003] At present, the only way to obtain water sources in desert areas to control desert greening ...

AI Technical Summary

Problems solved by technology

Because there are very few places with underground water sources, drilling wells requires a huge amount of money, and the success rate is very low, so the cost is too high and it is difficult to implement widely; the latter has limited water reserves and cannot solve the problem of water use in desertified areas. The cost is still higher
