River regulation ecological system

Abstract

An ecological system for river regulation is composed of ecological building blocks, biological building blocks and plants. Soil is fixed and water and soil loss is prevented through the mechanical effect (shallow root reinforcement and deep root anchoring) and the hydrological effect (rainwater interception, splash erosion weakening and runoff control) of plant roots planted on the ecological building blocks, the stability of the riparian zone is achieved, and meanwhile the natural ecological environment of the riparian is recovered through the diversity of plants. A biological membrane ecological environment which is not influenced by water flow and is suitable for the survival of fungi, metazoan and invertebrate organisms is formed by the submerged plants and the space of the gaps of the netted structures of the biological building blocks laid in a riverbed. The problems that substance exchange between water and soil is difficult after the riverbed is hardened, and underground water supply is insufficient are solved. The problem that harmful substances in sewage are not fully degraded due to the fact that microorganisms can be dispersed and diluted by water flow is solved, the purposes of overall coordination, self-maintenance, self-restoration and virtuous cycle of a river are achieved, and the natural ecological environment of the river channel is restored.

Description

technical field [0001] The invention relates to the technical field of river channel regulation, and mainly relates to a river channel regulation ecological system. Background technique [0002] The river channel mainly refers to the route through which the river flows, including an ecosystem composed of interrelated river embankments, slope protection, river beds and water bodies. With the acceleration of urbanization, the space of urban rivers is constantly being squeezed. In particular, the urban hydrological process is affected by the hard bottom. The ability to carry floods is weakened, and the problem of flooding after heavy rain is becoming more and more serious. On the other hand, excessively hardened and channelized rivers increase the difficulty of material exchange between water and soil, which not only damages the living environment of corresponding animals and plants, but also destroys the natural ecological environment of the river's self-repair. The increase...

Problems solved by technology

Microbial river treatment technology has the advantages of high efficiency, low cost, ecological energy saving, and environmental friendliness. However, if microbial strains are directly injected into the river, the microorganisms will be dispersed and diluted by the water flow, which is not conducive to fully degrading the harmful substances in the sewage.
