摘要
本文通过对云南产的东亚(主要是中国-喜马拉雅和中国-日本)各个属的分布区边界的划定,得出如下结论:(1)总的来说,‘田中线’是真实存在的,并且在限定中国-喜马拉雅和中国-日本属的分布边界时具有相当大的可靠性;(2)就与中国-喜马拉雅属以‘田中线’为其分布东界比较而言,中国-日本属以‘田中线’为其分布西界具有更高的可靠性。此外,本文还讨论了‘田中线’的成因以及其在云南的植物区系分区和种群划分上的意义。
After delimiting the boundaries of Eastern Asiatic genera (mainly Sino-Himalayan & Sino-Japanese ones) in Yunnan, we concluded as follows: (1) In general, ' Tanaka Line' is a real one which is effectively delimited the eastern boundaries of Sino-Japanese genera & the western boundaries of Sino-Himalayan ones; (2) In comparision with the Sino-Himalayan genera, the Sino-Japanese ones are more strict to ' Tanaka Line'. Furthermore, we discussed the origin cause of 'Tanaka Line' & its significance in the study of florististic regionalization in Yunnan and the delimitation of species.
