摘要
水生态风险评估可以为水环境和水生态保护决策提供服务,其技术问题和实践越来越引起高度关注。我国的生态风险评估工作尚处于起步阶段,如何开展评估尚缺乏具有操作性的技术指南,因而使从业人员无章可循。鉴于此,阐述了水生态风险评估的相关概念,并结合实践需要探讨了评估区域的划分、生态受体和评估终端的选择、暴露和效应分析、基于概率的风险分析等方面的技术问题,以期为该领域的技术人员开展此项工作提供参考。
The water ecology risk evaluation can help decision-making of water environment and water ecology protection, and its technical problem and practice arouse concerns. In China, the ecology risk evaluation is at a preliminary stage, and there is no feasible technical guidance for the practitioners to follow. Therefore, the relative concepts in water ecology risk evaluation is demonstrated, and the division of evaluation area, selection of ecological receptors and evaluation terminal, analysis of exposure and effect, risk analysis on the basis of probability are discussed by consideration of practice.
