摘要
通过对安徽金寨天马国家级自然保护区野外实地调查数据的统计分析,发现该区植物丰富,地理成分复杂,分布区类型多样。该保护区共有种子植物155科655属1676种(含种下分类单位),其中裸子植物6科8属13种,被子植物149科647属1663种。种子植物的组成中科、属的优势现象明显,以禾本科(Gramineae)、菊科(Compositae)、蔷薇科(Rosaceae)和唇形科(Labiatae)为优势科;以蓼属(Polygonum)、蒿属(Artemisia)等为优势属。从分布区类型看,在属级水平上有15个类型,属的分布区类型以北温带分布最多,其次是泛热带分布,温带分布显著多于热带分布。并且近年来在保护区及邻近地区发现多种植物新种和新变种。
For protection and rational utilization of the plant resources ,the flora of seed plants in Anhui Tianma National Nature Reserve in Jinzhai was fully analyzed in this paper .The results showed that the seed plant composition was relatively rich and the total 1676 species belonged to 155 families and 655 genera . Among them there were 6 families , 8 genera , 13 species in Gymnosperm ,and 149 families ,647 genera ,1663 species in Angiosperm .The phenomena of preponderant families and genera were obviously with Gramineae ,Compositae ,Rosaceae and Labiatae being dominant families .Besides ,at genus level ,there were 15 distribution types .The north temperate type is 21 .22% and the pantropic type is 15 .42% .The temperate elements were remarkable more than the tropic ones (371/199) ,indicating the character of the flora being temperate .The floristic origin was ancient ,geographical components were multiform and the distribution types were various .
