摘要: 关于划分我国亚热带的北界问题,意见虽不一致,但主张以秦岭淮河一线为界者较多,然而秦岭南北宽约300公里,此线应划何处较为合适,至今意见仍有分歧。

Abstract: This paper states the distribution of 177 species (including their varieties) of broadleaf woody evergreens on the Qin-lin Mountain, based on the viewpoint of specific phytogeographic or floral elements. It is possible to classify these species into two groups: One may be considered as that belongs to typical subtropical floral elements which are located on the southern slope of Qin-lin Mountain (Table 3); the other may be belong to the temperate ones which are found on the northern slope of the Qin-lin Mountain (Table 4). According to the distribution of above-mentioned floral elements, the northern boundary of the subtropical zone of China is located near 1000 m. above sea level on the southern slope of central part of Qin-lin Mountain, lying approximately from Latitude 33°5’, Wudu of Gansu Province, to 33°5’ North, the southern slope of the Funiu Mountain of Henan Province.
