摘要
对江西婺源的实地调查，并经过整理分析，对该县的木本植物区系进行了系统的研究，并对其区系成份和区系特点进行了分析。
Wuyuan County is situated at the northeast of Jiangxi Province, at the latitude of 29°01′～29°35′N and the longitude of 117°22′～118°11′E. It is one part of the East China Flora and lies in the north of “middle subtropical region” of China. According to the author′s study, about 615 species of woody plants(incl.varieties and forms) occur in this area, which belong to 94 families and 240 genera. Apart from some exotic and cultivated taxa, these species are turned into 235 genera. The total number of the genus can be classified into 13 types of floristic elements according to Prof. Wu Cheng Yih′s opinion. The percentage of tropical composition genera(42 6%) is much bigger than that of temperate ones(21 3%), which shows that the flora in Wuyuan County has a striking tropical feature.
