摘　　要：对中国的两个单种属明党参属和川明参属居群分布进行了调查研究,共调查湖北、江西、安徽、江苏和浙江的15个明党参居群,四川、重庆和湖北的12个川明参居群。调查二者居群所处生境特征,并统计了现存居群大小。研究发现,前人记载的湖北兴山地区分布的明党参实为川明参,表明这两个种的分布区出现了隔离,而非交叠,并推测二者的分布与长江水系有一定关系。Populations of Changium and Chuanminshen specific in China were investigated. 15 populations of Changium in Hubei, Jiangxi, Anhui, Jiangsu and Zhejiang province, with 12 populations of Chuanminshen in Sichuan, Chongqing and Hubei were investigated together. The character and size of habitat were researched in Changium and Chuanminshert. The results showed that the population in Xingshan city of Hubei province was not Changium as the formers recorded, but Chuanminshen. So the two species showed isolation in distribution, not overlapping with each other. The distribution of the two species is related to the system of the Yangtse River.
