城市河流浅水景观公园水质的富营养化灰色聚类法评价——以龙潭湖公园为例

Application of Grey Clustering Method in Eutrophication Assessment for Shallow Landscape Park of City River

在监测龙潭湖水质的基础上,选取透明度(SD)、高锰酸钾指数(CODMn)、总磷(TP)和总氮(TN)4个指标,采用灰色聚类法对其富营养化进行了评价,结果表明,这种方法简单、可靠,可有效提高信息的利用度,同时龙潭湖公园水体已处于中-富营养状态(Ⅳ级),进行治理已是刻不容缓。

Based on monitoring the water quality of Longtan Lake, SD, CODMn, TP and TN were selected as indices and gray clustering meth- od was adopted to evaluate the lake＇ s eutrophication. The results showed that this method is simple, reliable and can improve utilization de- gree of information, the Longtan Lake is between nutrition and eutrophication （ Ⅳ grade） that the management is urgent.
