Green corridor type regulating and storing system of wandering river in arid area

Abstract

The invention discloses a green corridor type regulating and storing system of a wandering river in an arid area. The green corridor type regulating and storing system includes a river channel regulating and storing belt arranged on a riverbed and slope stabilization belts arranged on river banks on the two sides. The river channel regulating and storing belt comprises aquatic vegetation, a cobblestone layer, a permeable paving layer, a vegetation planting soil layer and a water storing and collecting layer which are arranged sequentially from top to bottom. Each slope stabilization belt comprises a sand-proofing grid laid on the corresponding river bank and vegetation planted on the corresponding sand-proofing grid. When a flood season comes, the river channel regulating and storing beltin the green corridor type regulating and storing system provides a certain storage space and increases the capacity of flood discharging of a river channel. When a drought period comes, the purpose of recharging ecological base flow is achieved through water resources stored in the river channel regulating and storing belt.

Description

Technical field [0001] The invention belongs to the field of ecological regulation and storage of wandering river embankments in arid areas, and a corridor type regulation and storage system of wandering rivers in arid areas is designed. Background technique [0002] The Tarim River is located in the Taklimakan Basin to the south of the Tianshan Mountains and to the north of the Kunlun Mountains. It is the longest inland river in my country. It is the area with the most prominent water problems and the most vulnerable ecological environment in China. The replenishment water source in the basin is mainly alpine snow melt water, which has the characteristics of summer floods and winter dryness, fragile ecology, and serious desertification in the passing areas. In the past half-century, due to large-scale agricultural reclamation and high-intensity development of water resources in the headstream area of ​​the Tarim River, the number of source streams and the amount of water flowing...

AI Technical Summary

Problems solved by technology

Due to historical and geographical reasons, there were few studies on this type of river in the past, and most of the protection projects rarely achieved significant results. There is a risk of flooding, which poses a serious threat to agricultural irrigation and domestic water in populated areas within the Autonomous Region
