摘要
洲滩是鄱阳湖区分布广泛、数量众多和最为活跃的景观要素之一。研究洲滩的结构及动态变化、洲滩对鄱阳湖功能的影响,对鄱阳湖的治理有着重要参考价值。论述鄱阳湖的自然地理概况、土地利用动态,并着重分析洲滩的动态变化及其成因。结果表明:湖区大量泥沙淤积造成的洲滩,在一定程度上影响了湖流形态、泥沙冲淤和江湖水文关系等。因此,洲滩的改变导致鄱阳湖调蓄功能、生态功能等的变化,其分布和动态是反映鄱阳湖演变规律的重要信息。
Bottomland is a widespread, huge in number and most active in Poyang Lake area. Studying bottomland＇s structure, dynamics and influences on Poyang Lake is very important to harness the Poyang Lake. This paper states Poyang Lake ＇ s natural geographical conditions and the development of its land use, and emphatically analyzes the dynamic changes of the bottomland and its causes. The findings show that the large quantity of sediment deposition in the lake area has caused the growth of the bottomland, which to some extent has affected the shape of the lake, the sediment deposition and the hydrological relationship between rivers and the lake,etc. Therefore, the variation of the bottomland has led to the changes of the regulating and ecological functions of Poyang Lake, and Its distribution and dynamics are the key information to show the evolving laws of Poyang Lake.
