摘 要:鄱阳湖是中国第一大淡水湖泊,在调节长江径流、维护生态平衡、保持生物多样性及发展区域生态经济等方面有着举足轻重的作用.近年来,随着鄱阳湖流域人类活动及水文情势的发展变化,鄱阳湖水环境发生相应变化.2000年以后,特别是2004年以后,鄱阳湖流域由于城市化进程加速,湖区采砂,航道整治,以及水文循环处于干旱期或水资源消耗加剧等因素的综合影响,鄱阳湖典型站的水质指标较以前变化更为频繁和剧烈.然而,相对于其他封闭型的湖泊如巢湖、太湖等,鄱阳湖污染物的积累现象非常微弱.Poyang Lake is the biggest fresh water lake in China.It plays an important role in regulating the Yangze River Runoff, maintaining ecological balance, keeping biological diversity and developping regional ecological economy, etc. In recent years, with the development and change of human activities and hydrological situation in the Poyang Lake basin, the water environment of Poyang Lake has been changing correspondingly. After 2000, especially after 2004, due to the comprehesive influences of urban- ization accelerating, sand mining, waterway regulation, as well as hydrological cycle in dry season or water consumption increas- ing, the water quality index of the typical station of Poyang Lake changes more frequently and severely than before. However, rela- tive to other enclosed lakes such as Chaobu Lake and Taihu Lake in China, the pollutions accumulation phenomenon is very weak in Poyang Lake.
