Problems solved by technology

[0006] However, most of the above-mentioned existing technical methods can only be used on slopes with good soil quality, and it is difficult to support such heavy and heavy slopes with rare earth soil slopes dominated by sandy soil accumulation, small soil capacity, and poor stability. At the same time, the existing technology uses a large number of reinforced concrete, which also greatly increases the cost of water and soil conservation construction

Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below. All other implementations obtained below fall within the protection scope of the present invention.

[0041] According to the United States Universal Soil Erosion Equation (USLE): W=R*K*LS*C*P, where: W—soil loss (t / ha); R—rainfall erosivity factor; K—soil erodibility factor ; LS—slope length and slope factor; C—vegetation and crop management factor; P—soil conservation measure factor.

[0042] The rainfall erosivity factor R is related to the rainfall, and the soil erodibility factor K is related to the type and texture of the soil. To control the amount of water and soil loss on the slope of the rare earth tailings trace, it is necessary to control the slope length and slope LS, vegetation and crop management factors C. Soil conservation measures factor P three factors.

Abstract

The invention provides a water erosion prevention system and method for the ecology of a slope of an abandoned rear-earth mine land. According to the system, erosion of the slope of the abandoned rear-earth mine land caused by a water body can be prevented and controlled by arranging an obstructing belt and intercepting belts; a little sandy soil scoured by a water flow can be prevented from entering the water body by arranging a permeable layer; meanwhile the water flow can be led out by a diversion channel; and further, by arranging vegetation layers, water and soil can be effectively conserved, the slope is reinforced, and the maintenance of ecological balance is facilitated. Since the system is employed in the method provided by the invention, the method can effectively prevent and treat the water erosion of the slope and recover the ecological environment of the slope.

Description

technical field [0001] The invention relates to the field of water and soil loss prevention and control, in particular to an ecological waterproof erosion system and method for slopes of rare earth traces. Background technique [0002] Hydraulic erosion is the whole process of destruction, denudation, transportation and deposition of soil, soil or other ground components under the action of precipitation, surface runoff and underground runoff. It is an important type of soil erosion. [0003] There are two common types of hydraulic erosion: surface erosion and trench erosion. Surface erosion includes splash erosion, sheet erosion and rill erosion; gully erosion includes three erosion forms: source tracing, bank expansion and downcutting. However, on non-agricultural slopes, rills often become the initial stage of gully erosion. When the rill cuts down to the core soil and subsoil, it can gradually develop into a shallow ditch; the runoff further gathers in the shallow dit...
