摘要
本研究提出了流域水环境风险评价的主要特点,综述了水环境风险评价研究进展,提出应用GIS空间分析和暴露-响应监测等宏观与微观相结合的手段,通过选取关键节点构建风险传导路径链探讨风险传导趋势,打破了以往单纯的现状评价理念.旨在为风险评价与预测研究提供参考方向和新思路.
In the present work,major characteristics in risk assessment of basin water environment were summarized and research progress reviewed.Macro-microscopic combined methods such as GIS habitat analysis and exposure-response monitoring were used to calculate cumulative risk value in node by analyzing release direction,path chain and coefficient of risk at each node.This breaks away from traditional concept,to provide new directions and ideas for risk assessment and prediction in studies of basin water environment.
