清水河流域水质综合分析与评价

通过2018年4月、7月和11月在清水河流域布设32个采样点,监测F^-、TN、TP等6项水质指标,应用单因子评价法、综合污染指数法、灰色关联法、模糊综合评价法对该河水质状况作综合评价,并分析F^-是否参与评价时水质的变化情况。结果表明:当F^-不参与水质评价时,清水河各月水质污染程度为7月>11月>4月;当F^-参与水质评价时,水质污染程度为11月>7月>4月。模糊综合评价法的评价结果更符合实际水体情况,清水河上游—下游水质逐渐变差。当F^-参与评价时,清水河整体水质状况变差。

Analysis and Assessment of Water Quality in Qingshuihe River Basin

6 water quality indicators such as F^-,TN,TP,etc.in water samples from 32 sampling sites in Qingshuihe river basin were monitored in April,July and November 2018,the water quality was assessed by single-factor evaluation method,comprehensive pollution index method,grey correlation method and fuzzy comprehensive evaluation method,and the variation of water quality was analyzed whether F^-was evaluated in the water assessment.The results showed that when F^-was not evaluated,the pollution degree of monthly water quality in Qingshuihe river was July>November>April,and when F^-was evaluated,the pollution degree was November>July>April.The results of fuzzy comprehensive evaluation were more in line with the actual water conditions.The water quality gradually deteriorated from upper reaches to down reaches of Qingshuihe river.The water quality of Qingshuihe river became worse when F^-was evaluated.
