Fish habitat comprehensive protection system for upper stream, down stream, main stream and branch stream of reservoir

Abstract

The invention discloses a fish habitat comprehensive protection system for the upper stream, down stream, main stream and branch stream of a reservoir. The fish habitat comprehensive protection system comprises a reservoir upstream main stream fish habitat protection system, a reservoir upstream branch stream fish habitat protection system, a reservoir downstream branch stream fish habitat protection system and a reservoir downstream branch stream fish habitat protection system. The reservoir upstream main stream fish habitat protection system is arranged at the position, above a reservoir dam, of a riverway main stream. The reservoir upstream branch stream fish habitat protection system is arranged at the position, above the reservoir dam, of a riverway branch stream. The reservoir downstream main stream fish habitat protection system is arranged at the position, below the reservoir dam, of the riverway main stream. The reservoir downstream branch stream fish habitat protection system is arranged at the position, below the reservoir dam, of the riverway branch stream. According to the fish habitat comprehensive protection system, the overall healthy and sustainable development need of the ecological environment of the upper stream, down stream, main stream and branch stream of the reservoir is met, the river fish habitat protection theoretic and technical study system in China is filled and perfected, and social benefits, economic benefits and environmental benefits are all achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection of water conservancy and hydropower projects, and in particular relates to a comprehensive protection system for fish habitats in upstream and downstream reservoirs and main and tributary streams. Background technique [0002] Habitat usually refers to the region or environment type in which a certain organism or an ecological group lives and reproduces. In a broad sense, the concept of habitat not only includes the living space of organisms, but also includes all environmental factors in the living space. For fish, its habitat refers to the place where it maintains its normal life, growth, foraging, reproduction and other life cycles, including the range of waters necessary for fish to complete the entire life cycle process, such as spawning grounds, ropes, etc. Fish habitats not only provide the living space for fish, but also provide all the environmental factors that meet the ...

Problems solved by technology

At present, most of the protection, restoration, compensation and scientific research of river fish habitats in my country are in the stage of research, conception and design. The research theory and technology system of land protection is still not systematic, its protection effect is poor, it is not easy to operate, it has limited practical guidance for the project, and it is difficult to achieve the effective unity and balance of environmental benefits, economic benefits and social benefits
