摘要
在对大别山马宗岭自然保护区种子植物区系的统计和分析的基础上.着重研究了该植物区系的地理成分,将其划分为15个类型,并逐一讨论,为进一步研究大别山植物区系的起源和演化,更好地开发利用当地植物资源打下基础.
Mazongling Natural Reserve (one of the richest plant area of the Dabie Mountain) located at Jinzhai county in the west of Anhui Province, is the transitional region from the north subtropical to warm temperate zone. It is known that there are 1192 seed plants, which belong to 547 genera and 138 families. The studies are based on the origin and evolution of the flora in geological period. According to statistics and analysis of genera in the present flora, 547 genera can be divided into 15 distribution-types (con-taining 11 subtypes), which belong to five categories: 1) cosmoplitan genera 60 (10.9%),2)temperate genera 304 (55.5%),3)tropical genera 167(30.6%),4)ancient Mediterranean and Central Asia genera 2 (0.2%),5) Chinese endemic genera 14 (2. 6%). The studies show that the temperate genera have the highest percentage and the flora is related with every part of the world, especially closely related with North America and Japan.
