A channel engineering ecological environment influence multi-level comprehensive index system architecture

Abstract

The invention provides a channel engineering ecological environment influence multi-level comprehensive index system architecture. The method belongs to the technical field of ecological environment influence evaluation, wherein the four levels have a step-by-step inclusion relationship; the system comprises four influence process index subsystems, a 15-class influence type index module, 39 sets of impact factor indicators and a plurality of single-factor classification sub-item indexes are provided; an ecological environment influence path based on mechanism analysis and key indexes in mitigation countermeasure evaluation are systematically integrated; the transverse main framework covers the navigation channel project and affects the operation activities of the related areas; living environment change, species activity, ecological influence whole-process action mechanism, influence type depiction is carried out through a longitudinal main framework. Influence factor and single factorclassification item index fine description and analysis are carried out through transverse and longitudinal branch structures, and systematic display of channel engineering ecology influence evaluation results and identification, design, monitoring, investigation, analysis and evaluation of ecological channel construction key indexes are facilitated.

Description

(1) Technical field [0001] The invention relates to a multi-level comprehensive index system framework for waterway engineering ecological environment impact, and belongs to the technical field of ecological environment protection. (2) Background technology [0002] The ecological environment impact assessment of waterway engineering involves many indicators. Although there have been many studies on this at home and abroad, the indicators and indicator systems proposed are relatively macroscopic and scattered, and a systematic, comprehensive and applicable comprehensive indicator system has not yet been formed. For example: [0003] Xu Sudong et al. coupled the hydrodynamic model (ADCIRC) and the ecological fitness model (HSI) based on the existing research, established the relationship between the anchovy and the river clam and the hydrodynamic factors, and conducted a study on the characteristic species of the Yangtze River anchovy and the river clam. Ecological suitabili...

Problems solved by technology

[0012] Although the above research involves relevant indicators and index systems of the environmental impact of waterway engineering, the framework of the system is either relatively specific but narrowly involved, or macroscopic but lacks systematic and detailed indicators. In the analysis, design of mitigation measures, and follow-up ecological environment restoration and effect evaluation, the index system proposed in the above research and the traditional environmental impact assessment method alone cannot cover the key indicators of the whole process of operation activities, habitat changes, species activities, and ecological impacts. , and it is difficult to achieve the ecological high-quality development goal of detailed description and investigation and analysis by sub-action process, sub-influence type, sub-influence factor, and sub-indicator
