浙江豆科植物区系特点及地理分布研究

Flora Characteristic and Geographical Distribution of the Family Leguminosae in Zhejiang.

浙江共有豆科植物61属,181种,3亚种,7变种,3变型,其中栽培15属,57种,2变种,2变型。本文通过对各自然分布属在豆科中系统位置的分析,分布区类型的统计和与邻近地区豆科植物属、种的对比,认为浙江豆科植物区系种类丰富,起源古老,地理成分复杂,具有较明显的热带和亚热带性质,与邻近地区的关系密切,为一个开放型的植物区系。同时还探讨了地理分布格局,证实了以括苍山,仙霞岭一线为界的浙江东南部是华东、华南两植物区系的交汇地带。吴征镒将雁荡山、洞宫山一线以南的浙江东南一隅划为华南区系的范围是合理的。

There are altogether 61 genera, 181 species, 3 subspecies, 7 varieties and 3 forms about Leguminosae in Zhejiang, Which including cultivated 15 genera, 57 species,2 varieties and 2 forms. By analyzing systematic position of every natural genus, counting areal types, comparing with the other genera and species of Leguminosae in neighborhood and studying on migration and replacement, the flora of Leguminosae in Zhejiang is of rich variety, ancient origin, complicated geographical composition and more obvious characters of tropic and subtropic than the flora of the other spermatophytes in Zhejiang. This is an open flora with close relations to the flora in neighborhood. Also, this paper proves that the southeasten part of Zhejiang divided by the line of the Kuocang Mountains and the Xianxialing Mountains is a interweaved area of the E. and S. China flora. It is right that southeasten corner of Zhejiang divided by the line of the Yandang Mountains and the Donggong Mountains is put the range of the flora of S. China by Wu Zhengyi.
