鄱阳湖水质污染对湿地生态系统生态功能的影响

湿她内部生物、物理、化学组份之间的相互作用过程，推动湿地的形成和发育，是其生态结构和生态功能的物质基础。水是鄱阳湖湖泊及其湿地的主体要素之一，各种形式的水是参与湿地生态过程的主体成分．贯穿融于生态形成和系统运作的生物、物理、化学过程的每一个环节，湖泊水质的变化直接影响着湿地的生态过程，影响水域生态系统、湖滩草洲生态系统、农牧与生态系统食物链和食物网的质量．所以水质变化及污染是湿地生态功能衰退研究的核心内容之一。

THE FUNCTION ON WETLAND ECOSYSTEM OF POYANG LAKE'S WATER POLLUTION

The interaction processes between biological, physical, and chemical components inside wetland, which promotes the formation and development of wetland, is the material base of ecological structure and ecological function for the wetland. Water is the one of the main factors of Lakes and wetlands, and water in various formation is the chief elements in the wetland ecological processes and runs through the every step of biological, physical, chemical processes, which brings about the formation and action of the wetland. The change of water quality in the Lake affects directly on the wetland ecological processes and puts great impact on the quality of the wetland ecosystem, mead ecosystem, agriculture and farming ecosystem, and also on the food chain and network of the ecosystem. Water's quality change and water contamination are one of the core contents of the research on the decline of the wetland ecological function.
