松花湖水质富营养化现状研究

Studies on the Status of Eutrophication and Countermeasures in Songhua Lake

于2013年枯水期对松花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:松花湖水体已处于中营养阶段,由于环境温度和水体温度比较低还未出现富营养化现象.

Sampling was carried out in Marche 2013 in order to study structure of Chlorophyll-a, Total phosphorus,Total nitrogen, Transparent, Permanganate index and analysis of water quality in Lake Songhua. The results of study ： the Lake Songhua water body in the vegetative stage,due to environment temperature and water temperature low haven1 appear eutrophication phenomenon.
