Means and method for controlling deserts and sand storm

Abstract

The invention discloses a means and method for controlling deserts and sand storm on the aspects of wind control and water control, which are used for solving the problem that strong wind cannot be handled and water problem is not solved because sand storm is only controlled on the aspect of sand source control in the past. In the method, six windbreak walls are constructed according to the characteristic of the hierarchical structure of strong wind from a mountain pass close to the Karamay city to the exit of the Dzungarian Basin to a position close to two season rivers (from south to north) below the mountain slope of the Jiayu Pass to a mountain pass leading from the Badain Jaran Desert to the Tengger Desert. Strong wind is blocked and rubbed through the six walls, and the wind power is weakened greatly when arriving at desert areas, so that the sand storm is prevented. Water of the Yellow River and water of three rivers flowing from the Qilian Mountains to desert areas are scheduled scientifically, water is stored under the ground with enclosed impounding reservoirs and closed conduits, and is conveyed to desert areas for irrigating dropwise, so that water is saved, and the desert areas can be changed into grasslands and farmlands as fast as possible.

Description

[0001] Technical Field: Ways and Methods to Control Deserts and Sandstorms Background technique: [0002] In the decades since the founding of New China, the government has done a lot of work to prevent and control sandstorms. Such as the "Three-North Shelterbelt Project", and the project of returning grazing land to forests and grasses implemented in recent years. These projects have increased the vegetation coverage in areas where sandstorms occur and slightly reduced the number of sandstorms that occur each year. However, the effect of these measures is very limited, and it is impossible to solve the fundamental problem. Because these measures only reduce the source of sand and dust by increasing the vegetation coverage of the soil. And it can only be implemented in the desert or surrounding areas of sand, so the effect is limited. It cannot be implemented in desert areas, because there is no water in the desert, and there is no grass, so how can the degree of vegetation...

From these three items, it can be seen that this so-called "good method" is exactly the same as the previous one, and has little practical value.
