Wetlands are unique and important ecosystems which are formed under the interactions be-tween water and the land. They have very powerful economic values and ecosystem service functions. The sur-vey is designed to compare the vascular species compositions of Xixi Wetland Hong Garden and Jiangyangfan Ecological park in Hangzhou through field work and to analyze the differences and similarities between their species in regard to β diversity, growth and ecological pattern. The results show that the two regions had a high similarity in species composition due to the similar natural and human effects. However, differences and distinct features still exist. The findings reveal that there are low proportion of wetland plants in both regions, whicb suggest that the various landscapes should be well-protected in both region. For Xixi Wetland, more wetland plants should be planted and better wetland environment should be nurtured;and for Jiangyangfan Ecological Park, the types of local wetland species should be increased.%湿地是水陆交互作用下形成的独特而重要的生态系统，具有重要的经济价值和强大的生态服务功能．采用踏查法调查杭州西溪湿地洪因和江洋畈生态公园等两地的维管植物，旨在从β多样性和生长型、生态类型等方面来比较两地的种类组成的异同并分析其成因．调查发现：维管植物的β多样性及生态类型均显示两地物种组成有一定的相似性，这与两地同处于亚热带东部地区的杭州市以及相似的人类影响有关；但两地物种组成也有一定的差异，各具特色．西溪洪园和江洋畈公园的湿地植物分别为132种（53．7％）和111种（51．4％），占据总物种数量的比例较低．在今后的修复和建设中，两地现有的多样化的生态景观应该保护好，对于西溪洪园，建议多培育湿地环境和湿地植物；对于江洋畈生态公园，建议可适当增加本土的湿地物种．
