A continuous purification and utilization system for the receding water ecological zone of the trench into the river slope

Abstract

The present invention relates to the technical field of ecological protection, in particular to a system for continuous purification and utilization of ecological belts of river-inflow sloping ditches and receding water, which is composed of a water area management module, a water bank management module and a land area management module. The water area management module includes the deep tank-shoal reconstruction unit and the gravel tank purification unit, the water bank management module includes the ecological brick protection unit and the solidification protection unit, and the land area management module includes the cutting protection unit and the plant reinforcement reconstruction unit. The present invention adopts a modular structure, and different units can be used for the receding water ecological zone in different environments, and the solution to the problem is flexible, so it has a wide range of applications, and can be used according to the distance between the river channel and the residential area and the requirements for flood control. According to different standards, the construction cost is reduced under the premise of ensuring the basic functions, and the connectivity of material, energy and information exchange between land and water in the horizontal direction of the river is ensured by combining engineering transformation technology with biome configuration technology.

Description

technical field [0001] The invention relates to the technical field of ecological protection, in particular to a system for continuous purification and utilization of ecological belts in river-inflow slopes and ditches. Background technique [0002] Regressive ecological zone generally refers to the area where the water-land interface is intermittently submerged by water. As the link connecting aquatic and terrestrial ecosystems, the receding ecological zone can improve water quality in resisting floods, regulating runoff, maintaining water and soil, storing floods and fighting drought, degrading pollution, and purifying water. Aspects such as water ecosystems have irreplaceable effects of other systems. However, with the development of social economy, industry and agriculture, the continuous enhancement of human interference activities, and the increasing intensity of water resource utilization, the environmental capacity and ecological carrying capacity of more and more re...

Problems solved by technology

[0005] 1) The invention did not consider the specific situation of the river bank at the beginning of the design: the steepness of the river bank, the width of the river surface, the flow velocity of the water flow, poor adaptability to river sections with different appearances, and the purification cannot be performed according to the degree of erosion of the specific river bank. The structure is adjusted, the structure of the device is too solid, and the adaptability is poor

[0006] 2) This invention does not consider the cost problem in practical application: the protective structure of the river bank should be constructed according to the distance of the river course from the residential area and the standard of flood control requirements. For the river section in remote areas, the structure can be simplified according to the local actual conditions , on the premise of ensuring the basic functions, reduce the cost

[0007] 3) This invention uses a lot of masonry, reinforced concrete and other materials for slope protection. Although it has high stability, it destroys the connectivity of material, energy and information exchange between land and water in the horizontal direction of the river, and affects the original The purification function of some ecosystems

[0008] 4) This invention only considers the protection work under normal water level, but does not take into account the protection work of the river bank under the flood level, and there are potential safety hazards during the flood season of the river
