摘要:
根据2002-2004年洞庭湖水质监测数据,参照GB3838-2002中Ⅲ类水质标准,选用内梅罗水污染指数法和黄浦江污染指数对洞庭湖水质现状进行评价,结果表明:(1)洞庭湖水体的主要污染指标是总磷,总氮和粪大肠菌群;(2)黄浦江污染指数平均值为0.27,所以洞庭湖12个断面水质无黑臭现象发生;(3)枯水期西洞庭湖和南洞庭湖水质污染最严重,平水期西洞庭湖水质污染最严重,洞庭湖丰水期的污染程度小于平水期;(4)洞庭湖的大部分水体的水质主要处于轻度污染的状态,局部水体的水质在枯水期达到重污染的状态.

Abstract:
According to Basic Analytical Methods of Environmental Quality Standards for Surface Water in China (GB3838-2002),we used the 2002-2004 monitoring data to evaluate and characterize water quality condition of Lake Dongting, based on the application of comprehensive index methods such as Nemerow Index and Huangpu River Organic Pollution Index. The results are obtained as follows : (1 ) The main pollutants of Lake Dongting are total phosphorus (TP),total nitrogen (TN) and fecal coliform. (2) The mean Huangpu River Organic Pollution Index is 0. 27, indicating that the water quality does not have the black smelly phenomenon at twelve designated sections in Lake Dongting. (3) In western and southern Lake Dongting, the water pollution could be more serious during the drought water season, whereas during the normal water season in western Lake Dongting the water pollution is also bad. The water quality are generally better during the flood water season than those during normal water season. (4) Pollutants make a great contribution to the water quality of Lake Dongting; and the main sources are industrial effluents and domestic sewage. (5) The pollution condition of the main lake are not serious during 2002 -2004, while in certain water areas heavy pollution condition may occur during the drought water season. The investigations suggest that lake water quality has improved in recent years in response to changes in the land restoration of reclaimed areas and the construction of the Three Gorges Project.
Key words:  Lake Dongting  water quality assessment  Nemerow index  Huangpu River Organic Pollution Index
