摘要
通过野外调查和查阅资料,四川省屏山县老君山自然保护区有种子植物121科528属1 267种,其中裸子植物4科6属9种;被子植物117科522属1 258种。有39科种子植物属于泛热带分布类型,占总科数的44.83%;114属为北温带分布类型,占总属数的23.55%。保护区处于区系地域交汇处,与云南高原和滇黔桂地区属热带与亚热带的过渡性质的特征较不相符,而接近于横断山脉和华中、华东地区,区系表现为亚热带性质。
There are 1 267 species of seed plants belonging to 528 genera in 121 families, including gymnosperms (9 species, 6 genera and 4 families) and angiosperms (117 families, 522 genera and 1 258 species) in Laojun Mountain Nature Reserve in Pingshan County, Sichuan Province. Thirty-nine pantropic families account for 44.83% of the total families, while 114 north temperate genera amount to 23.55% of the total genera. The flora of Laojun Mountain Nature Reserve is close to the subtropical type which is spread in Hengduan mountains, Middle China and East China, though it is in the cross area of Yunnan, Guizhou and Guangxi characterized with the transition from tropical to subtropical zones.
