摘要: 中国种子植物特有属有268属,归78科,其中有8个单种属中国特有科。本文根据特有属的地理分布及与环境的关系,区分为9个分布型和23个亚型(包括本分布型),对各分布型和亚型进行了统计分析和详细阐述,讨论了分布区的间断和替代现象。提出特有科属分布型的主要特点。

Abstract: It is a high level endemism of chinese flora with 8 endemic families and 268 endemic genera.This paper deals with the distribution patterns based on their geographical distribution and the relationship with environrnents and the cartographic method.They are classified into 9 distribution patterns and 23 subpatterns,i. e. 1)S.China─S.Yunnan. 2)Yunnan Plateau─S.Yunnan,3)Hengduan Mts.─S.Xizang, 4) SW.China─C.China─E.China,5)SW.China─N.China, 6) C.China─E.China.7) N.China,8)Arid─region of NW.China and 9)Qinghai─Xizang plateau and have been made the statistics of number and the analysis are made.Various disjunctive and vicarious distribution phenomena are introduced in some genera or species endemic to China.3 basic characteristies of distribution patterns and main dispersal routes of endemic genera.i.e.(1).It is unequal in every region distributing mainly in the tropical and subtropical region of the south part of Qialing-Dabei Mts─Changjiang River and appearing 8 abundance centers.(2).It is radial dispersal from SW.China toward all directions and along several routes like to S.China─SE.China,C.China ─E.China,Northern China and S.Xizang.(3).There are various distribution forms as continued,disjunctive and vicarious areal.
