In this paper, the characteristics of the wetland ecosystem of the Poyang Lake national nature reserve are discussed through considerations of the hydrography, soil, biological composition and system function.

鄱阳湖是我国最大的淡水湖。鄱阳湖自然保护区以其独特的地形地貌，在亚热带湿润季风气候综合作用下，形成了一个多功能的复合湿地生态系统。根据湿地三条划分标准：有充分的水分、有机质含量较高的土壤及适应于此环境的植被。鄱阳湖自然保护区属淡水湿地生态系统。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
