摘　　要：通过实地调查,对峒河国家湿地公园的维管植物多样性进行了研究.研究结果表明,峒河国家湿地公园共有维管植物1 485种,隶属766属和179科,其中湿地植物(含水生植物)73科186属285种,分别占维管植物总数的40.78%,24.28%,19.19%;地理成分复杂,科的分布有11个类型,属的分布有15个类型;属的地理成分中,热带成分(327属,占46.25%)略高于温带成分(288属,占41.00%),植物区系呈现出一定的过渡特性.最后给出了相应的保护建议,为湿地公园生物多样性保护提供参考.The diversity of vascular plant species in Donghe National Wetland Park is described by field surveying. The results show that there are 1 485 species of vascular plant in Donghe National Wetland Park,belonging to 766 genera and 179 families. Among them,there are 285 Wetland plants （including a- quatic plants）,belonging to 186 genera and 73 families,accounting for 40.78% ,24.28% and 19.19% of the total amount of families,genera and species in Donghe National Wetland Park,respectively. The geo- graphic distribution is complex for 11 types of family distribution and 15 types of genera distribution. The flora in genera displayed significant tropical feature,with 46.25 % （including 327 genera） of tropical elements and 41.00% （including 288 genera） of temperate elements. The corresponding conservation strategies were proposed,aiming to provide reference for the biodiversity conservation of National Wet- land Park.
