| 摘要: |
| 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。 |

| Abstract: |
| 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 eatrophic 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. |
