摘　　要：应用领导者策略狼群算法-投影寻踪模型对北方某河流水质进行了综合评价。采样时间是2013年2-4月,采样点分别选取在该河流的上游、中上游、中游、中下游和下游等5个地方,选择了氨氮、全磷、全氮、COD、硝酸盐和亚硝酸盐六项水质指标。利用领导者策略狼群算法-投影寻踪评价法建立综合评价模型,并结合MATLAB编程求解,参照国标地表水环境标准,得出的评价结果为:从上游到下游的水质标准为国家地表水质二级、二级、四级、五级、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。In this paper ,a Projection Pursuit Method ,Wolf Colony Search Algorithm based on leader strategy is used for comprehen‐sive evaluation of a northern river water quality .The sampling time is February to April of 2013 ;the five sampling points were se‐lected in the upstream ,mid-upstream ,midstream ,mid-downstream and downstream of the river ;six water quality indicators ,inclu‐ding ammonia nitrogen ,total phosphorus ,total nitrogen ,COD ,nitrate and nitrite ,are selected .Projection Pursuit Method ,Wolf Colony Search Algorithm based on leader strategy ,is used to establish a comprehensive evaluation model ,which is solved by combi‐ning with MATLAB programming .Referencing to GB Surface Water Environmental Standards ,the evaluation result is obtained that the water quality level from upstream to downstream is the grade 2 ,2 ,4 ,5 ,5 ,respectively .This provides a scientific basis for water pollution control decision-making .
