摘    要:根据对蜡梅科植物的系统发育和分布规律的研究,结合古地理、古气候资料,讨论了蜡梅科的起源、演化和现代分布格局形成的规律。认为:中国泰岭以南、横断山脉以东为蜡梅科植物的现代分布中心。蜡梅科植物的起源地点可能在东亚,并在第四纪时通过白令陆桥到达北美;通过中南半岛、马来半岛到澳洲,并在各个洲独立发展,形成现在的东亚-北美间断分布及南北温带间断分布的格局。

关 键 词:蜡梅科  起源  演化  散布  分布  系统发育

Abstract:In the present paper, the origin, evolution and formation of modern distribution patterns of the Calycanthaceae were discussed based on studies of phyologeny,distribution, as well as the paleogeography and paleoclimatology. We considered that the current distribution center was from the South of Qinling Mountains to the East of Hengduan Mountains. Calycanthaceae might have originated from East Asia Region, and then migrated eastward to North America via Bering land Bridge during the Quaternary glacial period. At the same time,part of pre Calycanthaceae spread southward through the Malayan Peninsula to Java and Australia. and then developed isolatedly.Thus, the current disjunctive distribution of East Asia and North America Region,as well as South and North temperate zone has been formed gradually.
Keywords:Calycanthaceae  origin  evolution  distributiod
