Ecological slope protection in plateau pastoral area

Abstract

The invention relates to an embedded revetment of a plateau pastoral area, and belongs to the field of ecological restoration. The embedded revetment comprises a geogrid, an embedded concrete cell, a revetment substrate and revetment plants, wherein the geogrid is of a grid net structure; the geogrid is fixed to a slope of the revetment; the concrete cell is a concrete plate; a plurality of cavities and grooves are formed in one side of the concrete plate; the cavities penetrate through the concrete plate in the plate thickness direction; the side, back to the groove surfaces, of the concrete plate is fixedly connected with the geogrid; the cavities are filled with the revetment substrate; and the revetment plants are planted in the revetment substrate. According to the embedded revetment, defects of ecological revetments in plain areas are overcome, the revetment can resist severe conditions of high, cold and high-altitude areas, hydraulic scouring is effectively prevented, the function of fixing the slope is achieved, stability and landscape requirements of the ecological revetment are met, and the ecological environment of the water source region of Three Rivers is maintained.

Description

technical field [0001] The invention relates to an ecological slope protection in a plateau pastoral area, which belongs to the field of ecological restoration. Background technique [0002] The Qinghai-Tibet Plateau has unique climate and natural conditions, forming a unique grassland ecosystem, which covers almost all grassland types in my country, accounting for about 51% of the total land area of ​​the Qinghai-Tibet Plateau. Among them, alpine meadows are widely distributed in Qinghai-Tibet The unique vegetation types in the eastern part of the plateau and the surrounding mountains, with an area of ​​about 70 million hm 2 , accounting for nearly 50% of the available grassland on the plateau, is the main vegetation type on the plateau. Alpine meadow grass is of high quality and rich in nutrition. It is an important natural grazing pasture and animal husbandry base in my country. In recent years, with the continuous development of productivity, human beings have significa...

Problems solved by technology

[0004] The current ecological slope protection technologies include artificial grass, ecological bag slope protection, and grid ecological slope protection. The living conditions of vegetation are limited, and the overall stability is poor; the mesh ecological slope protection combines slope protection structure with plant slope protection, and the effect is better

However, most of the existing grid slope protections are only suitable for plain areas and cannot adapt to the special natural climate of plateau areas, and the existing slope protection structures have adversely affected the activities of livestock in plateau pastoral areas. Therefore, it is necessary to propose a method suitable for plateau pastoral areas ecological slope protection
