Abstract: Hongze Lake wetland is an important fresh water lake， one of the wetland ecosystem， but also in Jiangsu Province wetland ecosystem in the focus of protected areas， but with population growth and economic development accelerated， and wetland ecological environment have resulted in a serious problem， a concrete manifestation of for wetland biodiversity under threat， with an area of atrophy， habitat degradation and the management of confusion， which in a careful analysis of wetland ecosystems exist Hongzehu major problem on the basis of the proposed Lakes wetland ecological protection measures， namely: to reduce catch， cutting intensity， set up Nature Reserve; farmland to lakes， flood protection function; control the upstream water quality， set up monitoring systems and unified planning， improve the management 洪泽湖湿地是我国重要的淡水湖泊湿地生态系统之一，也是江苏省湿地生态系统的重点保护区域，但随着人口增长和经济发展的加快，湿地生态环境出现了严重问题，具体表现为湿地生物多样性受到威胁、面积萎缩、生境恶化和管理混乱，据此在认真分析洪泽湖湿地生态存在主要问题的基础上，提出湖区湿地生态保护对策，即:降低捕、伐强度，建立自然保护区;退耕还湖，保障调洪功能;控制上游水质，建立动态监测系统和统一规划，完善管理体制。
Macroinvertebrates were collected at 149 wetlands (n = 70 emergent; n = 79 forested) using a US Standard 30 mesh D-frame One sweep covered 5 m2 and was measured as one net width by two net lengths， repeated three times at each Twenty sweeps were proportioned among major vegetation zones throughout each The contents from the sweeps were collected in a 8 L plastic jar and preserved with buffered formalin at a rate of 10% of the sample Macroinvertebrate identification was completed at the Florida Department of Environmental Protection (FDEP) Central Laboratory， Tallahassee， FL， following standard operating procedures (FDEP Standard Operating Procedure #IZ-06 labs/sop) Identification was to the lowest taxonomic level
