摘要: 本文简述了鄱阳湖土地、水、气候和生物资源现状,分析了它们的特征。鄱阳湖是中国最大的淡水湖泊,但洪、枯水期湖水面积变化很大,枯水期由众多的子湖泊组成。它是一个过水性湖泊,年均迳流量高达1457×108m3,然而年际和月际变化很大,对长江水量调蓄作用不大,也不适时。总体水质良好,但已受到污染。鄱阳湖是本地区的日照时数、水体蒸发量和风能高值区,是气温调节器。鄱阳湖生物资源丰富,形成了完整的水域生态系统和水陆交替的湖滩草洲生态系统。

Abstract: This paper summarized the current situation on land, water, climate and the biological resources of Poyang lake, and the specific features has been analysed. The Poyang lake is the largest fresh water lake in China, the area covered fluctuates very much from the high water level season to the low. During the low water level season, the Poyang lake is consists of many small lakes. Though the annual average flowing surface water attains to as high as 1457 × 108m3, but the lake is just a passing water lake. Obviously, it does not play the effective role of the regulation of the flood storage for the Yangtze river, furthermore, it effects ofter not at a righi-time, nevertheless, the yearly and monthly variations are big enough. The over all water quality till keeps good, but the lake has been polluted already. The Poyang lake is a region of the high sunshine hours, evaporation values and wind resources of the district. The lake is an ais-temperature regulator. The biological resources is abundant in Poyang lake, makes it a complete waters ecosystem and makes it a complete lake beach-grassybar ecosystem that alternates of water or land.

Key words: Poyang lake, specific feature of natural resource
