A channel project ecological environment influence and countermeasure evaluation method based on mechanism analysis

Abstract

The invention discloses a channel project ecological environment influence and countermeasure evaluation method based on mechanism analysis. The method belongs to the technical field of ecological environment influence evaluation, aims at limitation of an existing evaluation method and related technology blank creation. The method comprises engineering construction checking and a change analysis method, a refined classification influence mechanism and countermeasure action analysis method, an ecological environment influence multi-level comprehensive index system architecture method, an ecological channel conformance evaluation index system architecture method, a long-time sequence satellite remote sensing tracking monitoring evaluation method and a superposition accumulation influence model analysis and evaluation method. The channel engineering ecological environment influence and countermeasure key action theory and related comprehensive index system architecture are enhanced; the evaluation result can be used for guiding identification, design, monitoring, investigation, analysis and evaluation of key indexes in ecological channel construction through the technical support of ecological channel evaluation index system architecture, large-range long-time satellite remote sensing data utilization and superposition accumulation ecological environment influence model analysis on ecological environment influence and countermeasure evaluation. The evaluation result can be used for guiding the identification, design, monitoring, investigation, analysis and evaluation of the key indexes in the ecological channel construction.

Description

technical field [0001] The invention relates to a method for evaluating ecological environment impact and countermeasures of waterway engineering based on mechanism analysis, and belongs to the technical field of ecological environment impact evaluation. Background technique [0002] As an important mode of transportation, shipping has always undertaken heavy passenger and freight tasks, especially the The task of transporting global resources and materials has been fulfilled. [0003] According to reports, the cost of shipping is only 1 / 4 of that of road transportation and 1 / 2 of that of rail transportation, and the environmental pollution caused by road and rail transportation is 23 times and 3.3 times that of shipping, respectively. Therefore, all countries in the world attach great importance to the development of ocean, coastal and river shipping functions. Take rivers as an example. , China has carried out large-scale waterway improvement projects for the Yangtze Riv...

AI Technical Summary

Problems solved by technology

[0008] (4) In the article "Ecological Measures and Technical Prospects for Yangtze River Trunk Waterway Harnessing", Liu Huaihan and others expounded the response of Yangtze River waterway governance to ecology, analyzed how to coordinate the development of waterway capacity expansion and ecological environment, and proposed to establish a scientific ecological waterway construction The basic structure and evaluation system, the specific technical path is not given in the article

[0010] Based on the above analysis, my country still lacks ecological environment impact and countermeasure evaluation methods suitable for scientifically and systematically tracking and guiding the construction of ecological waterway projects.
