清凉峰与邻近地区植物区系关系的探讨

A Study on the Floristic Relations between Mt.Qingliangfeng and Its Adjacent Regions

将清凉峰自然保护区植物区系作为一个独立的植物区系单位与邻近地区植物区系共有种进行对比分析，揭示了清凉峰植物区系是华东植物区系的组成成份。本区与邻近山地植物区系最为密切的为西天目山、黄山，其次为大别山、庐山，再次为鄂西神农架。

Mt.Qingliangfeng locates at the boundary of Anhui and Zhejiang provinces.The floristic relationship between Mt.Qingliangfeng and its adjacent regions was analysed on the floristic elements of shared plant species using contrastive method.The area investigated is the closest to floristic region of East China,next to regions of Central China,South China,the boundaries among Yunnan,Guangxi and Guizhou provinces,North China,South-west China,Japan sequencely,but with less relationship with plaeotropical zone,North-east China,Qinghai-Tibet plateau,North-west China.Hance,the flora of Mt.Qingliangfeng should be considered as an important part of the Flora of East China. The similarity coefficient between this regional flora and that of Mt.West-Tianmu,Mt.Huangshan,Mt.Tiantangzhai,Mt.Lushan,Mt.Shennongjia are 78 25%,73 65%,58 66%,57 22%,47 29%,respectively.
