中国大陆与台湾画眉亚科鸟类渊源初探

中国现有画眉亚科鸟类１３１种，占世界种数（２８２种）４７％，其中有１３种为海峡两岸（大陆与台湾）共有。海峡两岸画眉类鸟类的分布有两种情况：连续性分布或间断性分布。这种既连续又间娄的分布特点，表现在来眉类鸟类在海峡两的种内及种间的差异上，同时也体现了台湾与东喜巴拉雅地区之间来眉类鸟类的亲缘关系。在地持、气候、植被环境等诸多因素历史变迁的共同影响下，形成了画眉类鸟类在台湾岛上特有的５个种及１２个亚种。

A PRIMARY PROBE INTO THE RELATIONSHIP OF CHINESE TIMALIID BIRDS IN TAIWAN AND ON MAINLAND CHINA

China has 131 species of Timaliinae, 47% of the world total. Among them, 13 species are found concurrently both in Taiwan and on mainland China,and patterns of their distribution showing either in continuity or in fragments. Under such a pattern of distribution, it appears both the interspecific and intraspecific differentiation of those timaliid birds in Taiwan to those on mainland China and a relatively close relationship of those timaliid birds between Taiwan, southern China, and even eastern Himalayas. And, due to the climate changes, habitat variations, and other factors, 5 species and 12 subspecies of the timaliid birds have seperated endemically in Taiwan.
