落马湖水质及富营养化安全性分析

Status of eutrophication and water guality safety in Luoma Lake

落马湖属于小型景观水体,具有自净能力差、容易产生水体富营养化的特点。于2014年4月(枯水期)对落马湖水体进行了叶绿素a(CHl-a)、总磷(TP)、总氮(TN)、透明度(SD)、高锰酸盐指数(CODMn)等理化因子测定;分析松花湖水质现状。结果表明,落马湖的水体已重度富营养化,安全等级达到Ⅴ级。

Luoma lake belongs small-sized landscape water,it＇s self purification ability is poor and easy to bring water eutrophication.In April 2014（low-water season）,the water of Luoma lake including chiorophy11-a,total phosphorus,total nitrogen,transparent,permanganate index,and other physical and chemical factors were analysised.Results showed that the water of Luoma lake had severe eutrophication and the safety class was to grade V.
