摘　　要：目的:研究百蕊草群落物种多样性,调查百蕊草寄主种类。方法:在句容天王、句容茅西、句容茅山、滁州花山、来安长山、来安施官、来安七里等地,对百蕊草集中分布区域进行群落学和百蕊草寄主种类调查,然后采用物种多度、物种丰富度指数、物种多样性指数、群落均匀度指数分析群落物种多样性与百蕊草多度的关系。结果与结论:百蕊草喜光照,喜温暖湿润气候,喜酸性至中性肥沃壤土。百蕊草多分布于含水量充足的坡地,其群落主要为草本群落或有稀疏小灌木的草本群落。百蕊草群落物种多样性以来安长山和滁州花山居群最高,句容茅山居群最低。百蕊草多度与群落个体数呈正相关,而与群落丰富度、群落盖度、群落多样性Simpson指数、Shannon-wiener指数、Pielou均匀度指数呈负相关。百蕊草寄主种类广泛,共发现其寄主有11科28种植物,其中5科为百蕊草寄主新发现科,新发现百蕊草寄主18种。Objective： To study species diversity and the host of Thesium chinense community. Method： The investigation on phytocoenology was carried out on the T. chinense community in 7 areas of Anhui Province and Jiangsu Province. The correlation be- tween species diversity of community and T. chinense abundance was analyzed regarding to the abundance of species, the abundant in- dex of species, species diversity index and comnmnity even index. Result and Conclusion： The results showed that T. chinense liked light, warm climate, liked acidic to neuter soil. The majority of T. chinense distributed in the humid wasteland and herbaceous community. There was a positive correlation between the abundance of T. chinense and the unity numbers of community, and a negative correlation between the abundance of T. chinense and the abundance, coverage, diversity index, Pielou even index of community. T. chinense host species was various. This investigation found 28 host species belong to 11 Families, among them 5 Families and 18 species were found for the first time.
