中国湿生芦苇群落退化研究现状

芦苇群落是湿地生态系统的先锋植物群落,作为湿生、半湿生生态系统的主要生产者,是水体生态系统中物流和能流的物质基础,具有维持生态系统生物多样性和环境稳定性等功能。由于社会经济发展与生态保护之间的矛盾,湿地芦苇群落受到严重破坏。综述了芦苇群落退化的主要现状,同时总结分析了芦苇在水分、盐分、水质等逆境胁迫下,以及土壤养分等与群落生长的关系,认为针对种群退化研究的整体水平还需微观层次的探索和支持。

Current Status of Studies in Degraded Humidogene Reed Community in China

Reed is a pioneer plant growing in rivers,lakes and silt beaches.As a primary producer in wetland ecosystem,it is the physical basis of energy flow and mater flow in wetland ecosystem,with functions of maintaining ecosystem diversity and the environment stability.As the population grows rapidly in recent years,the conflict between socio-economic development and ecological protection becomes prominent,and wetland reed communities are suffering more serious damages than ever before.The degradation of reed community was reviewed with an analysis of the relations between soil nutrients and growth of reeds under stresses of water,salt and water quality.It was suggested that more studies at microscopic level to support the studies of reed community degradation.
