摘要
在对黄家湖环境监测的基础上,选用综合加权指数模型,对湖泊进行富营养化评价,并提出水质保护措施。评价指标参数主要有叶绿素a、总氮、总磷、化学需要量、透明度等,评价时由参数实测值得出单参数,加权计算综合值,最后按分级标准判断营养状况类别。评价结果表明,黄家湖水质重度富营养化。针对调查及评价结果,结合当地的实际情况提出了黄家湖富营养化综合防治对策。
Weighted composite index method was used for the eutrophication assessment of Huangjia lake with the environmental monitoring data.Five indices including Chl-a,SD,TN,TP,COD were chosen to give rise to single parameters,based on their measured values.Then composite values by weighted-calculating were used to evaluate the eutrophication level of the lake according to the corresponding grading standard.The analysis results demonstrated that the Huangjia lake was hyper-euthophicated,and countermeasures of eutrophication were also discussed with actual conditions.
