摘　　要：为了积累和完善贵州湄潭湄江湖国家湿地公园中植物的基础数据,采用调查样带和样方相结合的方法,对该湿地公园内湄江湖及其上游河流和沼泽湿地中的植物开展了野外调查,分析了湄江湖及其上游河流和沼泽湿地中维管植物的物种组成和地理成分。研究结果表明,在湄江湖及其上游河流和沼泽湿地中,共记录了82科191属242种维管植物,其中,有2种为国家二级保护物种,有15种为外来入侵物种,有2种为贵州省特有分布物种;植物群落主要由被子植物组成,禾本科(Gramineae)和菊科(Compositae)物种是广泛分布的物种,分别有22属26种和21属27种;湿地中的维管植物主要由草本植物组成,草本植物的物种数量占维管植物总物种数量的70.66%;湿地中维管植物的地理成分复杂,中国特有分布属匮乏,维管植物区系的个性特征不明显。In order to accumulate and improve the basic data of plants in Guizhou Meitan Mejiang Lake National Wetland Park,the method of combining survey sample belt and sample square was adopted,the species composition and geographical composition of vascular plants in Mejiang Lake and its upstream rivers and marshes were analyzed by field investigation.A total of 242 vascular plant species belonging to 82 families,191 genera were recorded in Mejiang Lake and its upstream rivers and marshes,there were 15 alien invasive species and 2 endemic species in Guizhou province,the plant community was mainly composed of angiosperms,and Gramineae and Compositae are widely distributed species,the vascular plants in wetlands were mainly composed of herbaceous plant,and the herbaceous plant species accounted for 70.66%of the total vascular plant species.The geographical composition of vascular plants in the wetlands was complex,the endemic distribution in China was scarce,and the characteristics of vascular plants were not obvious.
