Landscape river restoration system

Abstract

The invention relates to a landscape river restoration system. The landscape river restoration system comprises a clay layer, a sand and gravel layer, a soil layer and an organic matter layer which are successively arranged on the surface of each river slope, and also comprises an ecological restoration blanket which is arranged on a river bed and used for restoring contaminated sediment, whereinthe surface of each organic matter layer is provided with a vegetation layer; each vegetation layer is successively provided with a drought-enduring plant layer, a waterlogging-enduring plant layer, ahydrophilous plant layer and an aquatic plant layer from top to bottom; and the ecological restoration blanket successively comprises a surface layer, a plant-growing layer, an adsorption layer usedfor adsorbing pollutants in water and a carrier layer from top to bottom. Compared with the prior art, the landscape river restoration system provided by the invention has the following advantages: byadoption of a layered design idea, different varieties of vegetation are designed according to plant growth characteristics, and the ecological restoration blanket is arranged at the bottom part of the river bed and can be covered on the sediment of a contaminated water body to isolate pollutants in the sediment from entering the water body, so the purpose of river restoration is achieved; the effect is significant; meanwhile, the landscape river restoration system provided by the invention has simple structure and low cost and facilitates large-area popularization and application.

Description

technical field [0001] The invention relates to the field of urban greening construction, in particular to a landscape river restoration system. Background technique [0002] my country's urban rivers are generally polluted and are still developing rapidly. Water pollution exacerbates the shortage of water resources, directly threatens the safety of drinking water and people's health, and affects industrial and agricultural production and crop safety, especially urban rivers, which are flowing in the urban landscape and are closely connected with the living environment of urban residents. And relatively open complex ecosystem. Rivers have a certain ability to self-purify and recover from external sources of pollution. However, due to the large number of residents along the urban rivers, the production and life of residents have a huge impact on urban rivers, resulting in the continuous degradation and loss of urban river ecological functions, black odor, and mosquito breedi...

AI Technical Summary

Problems solved by technology

Through measures such as water and soil conservation, water diversion, and wetland restoration at the source of rivers, the ecological system in some areas has been improved, but the effect is not obvious, especially the restoration requirements of landscape rivers cannot be met, and the problem of river pollution has not been fundamentally controlled.
