根据第二次全国湿地资源调查成果,分析了长江流域上游、中游和下游的湿地资源及其湿地保护现状,重点论述了长江流域内国际重要湿地和国家重要湿地的分布数量、湿地面积、保护形式等情况,同时通过对流域内423个重要湿地受威胁状况及其影响面积的调查分析,总结了长江流域湿地面临的主要威胁,探讨了长江流域湿地保护对策,旨在为长江流域湿地保护与综合治理策略研究将提供参考。
According to the field survey data of the second national wetlands inventory project,this study analyzed the wetland resources and conservation status of the Yangtze River basin,including upstream,midstream and downstream.The information of wetlands of international and national importance in this region,e.g.,number,distribution,area,forms of conservation,etc.,was introduced.Meanwhile,the major threats to the wetlands in Yangtze River basin were revealed by investigating the threatened status and impacted area of 423 important wetlands within the river basin.And the wetland protection countermeasures were discussed.The results will provide basic data and related information for wetland protection and comprehensive management strategiess and tudy in the Yangtze River basin.
