沉积物质量综合评价及应用证据权重法的案例分析
Integrated Sediment Quality Assessment:A Case Study Based on Weight of Evidence Approach

查看参考文献55篇

文摘 水体沉积物是水生生态系统重要的组成部分,沉积物污染将影响整个水生生态系统,因此有必要构建科学全面的水体沉积物质量评价方法,为环境污染修复与监管提供科学依据。已有文献报道了多种沉积物质量评价方法。其中,证据权重法通过对不同的证据进行测定与整合,弥补了传统评价方法的不足,可以对沉积物质量进行科学全面的评价。本文对证据权重法中化学分析、生物毒性和底栖生物群落结构3种证据的测量方法、赋权方法、证据整合与信息解译方法进行了系统评述,并以淡水河为例介绍了用多目标决策理想点法(TOPSIS)整合数据进行沉积物质量综合评价的方法。
其他语种文摘 Sediment is an important part of aquatic ecosystems,and its pollution can affect the health of the whole ecosystem. Therefore,it is essential to develop a proper sediment quality assessment method,which can facilitate pollution control,and provide a scientific basis for further remediation of contaminated aquatic environments. Various sediment quality assessment methods have been proposed in the past. Among those assessment methods,weight of evidence approach measures and integrates different lines of evidences,which can make up the drawbacks of those traditional simple evaluation methods and provide scientific and comprehensive evaluation of sediment quality. This paper introduced the three major lines of evidences including sediment chemistry,toxicity and benthic community, as well as weighting methods and relevant information integrating methods. A detailed procedure of sediment quality assessment was introduced here with Danshui River as an example by using technique for order preference by similarity (TOPSIS) to integrate data.
