河流水质评价综述

River Water Quality Assessment

随着我国对水环境、水资源保护和供水安全的日益重视,河流水质评价的重要地位也逐渐凸显出来。该文从河流水质评价的研究背景入手,对国内外研究进展、国内外研究现状的比较、评价方法的简介和优缺点、权重的选取及分析、指标的权重折减等几方面进行了系统地述评。在此基础上,指出水质评价今后应优化的方向,除了定性定量评价水质之外,在评价方法上,应将各评价方法的优缺点进行整合,相互借鉴改进,使评价结果更合理;此外,在选择评价方法时,应选择与我国河流以及研究对象相适应的方法,切忌一味学习国外方式方法。

With the emphasis on water resources protection and water supply safety, river water quality evaluation is highlighted. Firstly, the paper introduces the research background of the assessment. Secondly, a detailed introduction is made on comparison between domestic and international research progress, advantages and disadvantages of the evaluation methods, and the weight selection and analysis. Lastly, based on above discussion, it pointed the optimized direction in the future. In addition to the qualitative and quantitative evaluation of water quality, the advantages of each evaluation method should be integrated, and the evaluation results should be more reasonable. Moreover, research methods should be adapted to the object.
