- 鄱阳湖观鸟
- 作者： 林健 来源：大自然 年份：2002 文献类型 ：期刊 关键词： 家鸡 和谐共处 鄱阳湖 保护站 保护区 观鸟 干涸 翠鸟 鱼塘 金翅雀
- 描述：恶鸟就在村边干涸的鱼塘里觅食,旁边是一群群的家鸡,大家相安无事,和谐共处。然而更让我们兴奋的是那些随处可见的小鸟。离我们最近的是金翅雀,每天傍晚它们密密麻麻地站在保护站附近的电线上,像一群小哨兵。有时候来晚了的,几乎找不到位置,要费一些工夫才可以挤出一块地方。保护站附近座落着一个个小村子,村子周围是一片片

- 鄱阳湖水文特性分析
- 作者： 徐德龙 熊明 张晶 来源：人民长江 年份：2002 文献类型 ：期刊 关键词： hydrologic composition Poyang property action Lake storage flood
- 描述：The Poyang lake is currently the largest freshwater lake in China. Hydrologic properties of this lake, including precipitation, runoff, flood, sediment transport and so on have been analyzed on basis of large amount of measurements. Variation of these properties within a year and among years and the regional distribution are explored. The encounter probability of the outflow from Poyang Lake with that from Changjiang River is computed and the detention volume of Poyang Lake is analyzed. In accordance with water balance theory, the detention storage volume of Poyang Lake and Changjiang River corresponding to the annual maximum 60-day flood volumes in 9 typical heavy flood years of 1968, 1969, 1973, 1980, 1983, 1996 and 1998 have been calculated. The detention storage capacity of both the Lake and the River ranges from 5.6 billion to 16.5 billion m\+3, 11.5 billion m\+3 at average. Among which, the detention storage capacity of Poyang Lake is 9.5 billion m\+3, accounting for 82.6%. Poyang Lake has played a very important role in detaining floods from the five rivers of the Lake system as well as floods on the river section from Changjiang to Bali. There would have more frequent and more serious flooding on the middle and lower Changjiang River, especially in the region around Hukou if there were no Poyang Lake to detain and store the floodwater.
