Abstract

The invention discloses a classification mechanism analysis method for finely generalizing the channel engineering ecological environment influence and belongs to the technical field of ecological environment influence evaluation. A set of generalized models are adopted to classify and analyze the ecological environment influence action mechanism of bank protection, bottom protection, dredging andbeach cutting, spur dike and submerged dike projects in construction and operation, analyze an action mechanism and an interference path of the influence of the channel operation period on the ecological environment, and identify the channel engineering construction and operation superposed to accumulate action factors of ecological environment influence, the key effects of representative engineering influence prevention and countermeasures alleviation are developed, a channel engineering ecological environment influence mechanism analysis method and process based on ecological habits and egglaying characteristics are established, a scientific, systematic, comprehensive, effective, fine and generalized mechanism analysis method support is provided for comprehensively, completely, finelyand deeply analyzing a channel engineering ecological environment influence mechanism, proper countermeasure measures for preventing and alleviating adverse effects are further derived, the design andplanning of ecological waterway are carried out, and the scientific, systematic, comprehensive, effective and precise mechanism analysis method support are provided.

Description

technical field [0001] The invention relates to the technical field of ecological environment impact assessment, in particular to a classification mechanism analysis method for finely generalizing the ecological environment impact of waterway engineering. Background technique [0002] Waterway construction has both positive and negative impacts on the ecological environment. Its positive impact is that it has certain ecological benefits during the operation period, which is specifically reflected in: it can improve and stabilize the river regime conditions, reduce the degree and frequency of river habitat mutations, and reduce the number of water traffic accidents by reducing navigational factors and improving navigation conditions. In order to reduce the probability of ship oil spills and dangerous cargo accidents, and reduce the risk of environmental damage; its negative impacts include not only the construction of bank revetments, bottom protection, damming, beach cutting...
