鄱阳湖是我国最大的淡水湖泊,湖区湿地面积2698km2,是我国湿地生态系统中生物资源最丰富的地区之一。长期以来由于人类不合理的开发利用,导致了鄱阳湖湿地面积和景观结构发生了很大变化,湿地生态功能也遭到严重破坏,生物多样性不断减少。分析了鄱阳湖湿地生物多样性现状、及其面临的威胁,并提出了鄱阳湖湿地生物多样性保护及其可持续利用的主要对策。

The wetland in the Poyang Lake area is the largest fresh water lake wetland in China, and its wetland is about 2 698 km^2 in area. It is one of the districts which have very rich biological resources. However, owing to man＇s unreasonable utilization for a long time, the wetlands have changed a great deal in area and landscape structure, the ecological function was seriously affected and menaced, biodiversity rapidly reduced. The situation of wetland biodiversity in the Poyang Lake area and the threatening of wetland biodiversity is facing are analyzed, and then the main countermeasures of conservation and sustainable utilization for biodiversity of the Poyang Lake area are put forward.
