摘 要 ：清凉峰自然保护区有维管束植物181科,601属,1228种,是安徽植物资源集中地之一。区系成分起源古老,孑遗种多,保存着丰富的珍稀、濒危植物。种子植物区系地理成分复杂,各类热带成分、温带成分、中国特有成分分别占本区种子植物属总数的33.6%、62.96%、3.44%,显示了本区植物区系的亚热带特性。本区植物区系97.6%的成分与华东植物区系共有,且含华东特有种111种,具有典型华东植物区系特征。本区植物区系与西天目山、黄山植物区系关系最密切,其次为大别山和庐山,再次为神农架。

Abstract:Qingliangfeng Nature Conservation (QNC) is an important part of the Tianmu mountains. The basic floristic characteristics are as follows: 1) The floristic elements are comparatively rich. 2) The flora is ancient origin, with rich relic elements. 3) The new records of the floristic elements from Anhui are comparatively rich.In this region, the genera of seed plants of temperate distributional patterns make up 62.96%, taking a predominated position, and the genera of tropical distributional patterns make up 33.6%. The results show: The flora of this region has the characteristics of the subtropical flora and the floristic geographical elements are complex.By means of contrasting and analysing the shared species of the floristic elements between QNC and the adjacent regions, the results show: This region is the closest to the floristic region of East China. Hance, the flora of QNC should belong to the typical Flora of East China.By analysis of the floristic relationships between QNC and adjacent mountains the similarity coefficients between this regional flora and Mt. West-Tianmu, Mt. Huangshan, Mt. Tiantangzhai of Dabie mountains, Mt. Lushan and Mt. Shennongjia are in sequence order of 78.25% 73.65%, 58.66%, 57.22%, 47.29% respectively.
