水利工程对水环境生态影响评价综合体系的构建与研究

Construction and Research of Comprehensive Evaluation System of Ecological Impact of Hydraulic Engineering on Water Environment

为深入评估水利工程建设对水环境生态健康的影响,基于湖泊群生态系统结构特征运用层次分析法,筛选出生态系统健康综合评价指标,对湖泊水质的生态健康水平进行评价,建立湖泊水生态系统健康综合评价指标体系。这套体系不仅有助于改善湖泊生态系统的监测方法,还能及时反映出湖泊水质的健康状况。并通过分析珊泊湖连通湖泊群之前和之后的各项生态指标的变化,综合评估工程的实施效果,探讨工程建设对湖泊水环境生态的具体影响,为后续水利工程规划和管理提供重要的决策支持。

In order to deeply evaluate the impact of water conservancy project construction on water environment and ecological health,based on the structural characteristics of lake ecosystem,AHP was used to screen out the comprehensive evaluation indicators of ecosystem health,evaluate the ecological health level of lake water quality,and establish the comprehensive evaluation index system of lake water ecosystem health.This system not only helps to improve the monitoring methods of lake ecosystems,but also reflects the health status of lake water quality in time.By analyzing the changes of various ecological indicators before and after the connected lake group of Shanbo Lake,the implementation effect of the project is comprehensively evaluated,and the specific impact of the project construction on the water environment and ecology of thelake is discussed,which provides important decision support for the subsequent water conservancy project planning and management.
