鄱阳湖富营养化调查与评价

INVESTIGATION ON POYANG LAKE WATER POLLUTION BY EUTRPHICATION

为了较全面地了解鄱阳湖水体的富营养化现状,于1992年5月16日～6月30日（平水期）和1993年1月5日～2月4日（枯水期）在各河入湖口、湖区、候鸟保护区及长江九江大桥断面进行了调查。结果表明:平水期,88.9％的湖区和10％的河口属富营养,11.1％的湖区和90％的河口属中～富营养;枯水期,100％的湖区和50％的河口属富营养;赣江南支口、信江东支口及湖区蛇山至都昌（鄱阳湖南部部分区域）营养物质的含量较大。建议控制五大河流及其区间地表径流中的营养物质对鄱阳湖的影响。

Based upon the data investigation from May 16, 1992-June 30, 1992 and January 5, 1993-February 4, 1993 in Poyang Lake district, the status of water quality in Poyang Lake is assessed with the results being: (1) the mean water level period, some stations, covering 88. 9% of the lake area, belong to eutrophic type, 11.1% together with 90% of inlets belong to medium-eutrophicqtion; (2) in low water period, 100% of lake area and 50% of inlets belong to eutrophic type; (3) TP,TN are the main pollutants.
