摘要
水质评价问题是目前研究的一个热点问题,属于多因素的综合评价问题。应用人工蜂群-投影寻踪评价法对南方某河水质进行了综合评价。采样时间是2013年3-4月,采样地点选取了该河流的上游、中游和下游3个地方,并且根据实测资料选择了氨氮、全磷、全氮、COD、硝酸盐和亚硝酸盐6项评价指标。参照国家规定的地表水环境标准,利用人工蜂群-投影寻踪评价法建立综合评价模型,利用MATLAB编程求解。评价结果为:从上游到下游的水质等级标准为国家地表水质一级、四级、五级。这为该地方政府在制定河水污染治理决策等方面提供了科学依据。
Water quality evaluation is a hot issue in the present study, which is part of a comprehensive evaluation of multiple factors. In this paper, the comprehensive evaluation of water quality of a certain river in southern China is conducted by using artificial bee colony-projection pursuit. The sampling time is from March to April, 2013 and the sampling sites is in the upstream, midstream and downstream of the river. Six evaluation indicators, i.e. ammonia nitrogen, total phosphorus, total nitrogen, COD, nitrate and ni- trite, are selected according to the measured data. A comprehensive evaluation model is establised By using artificial bee colony-pro- jection pursuit and referencing to the national surface water environmental standards. The above model is solved by MATLAB. The evaluation result is that from upstream to downstream, the water quality is at the 1st, 4th and 5th grade of the national surface water quality standard. It will provide a scientific basis to develop water pollution control decisions.
