浙江珍稀濒危保护植物的地理分布及其区系特征

本文分析了浙江珍稀濒危保护植物56种的地理分布和51属的分布区类型及其区系特征,其结果如下: 1.本区存在较多的我国特有属,单型属、少型属的事实,说明浙江省的珍稀濒危植物区系的古老性和相对原始性。2.根据51属的分布区类型的分析,其属具有明显的温带性质,而56种的地理分布则以亚热带区系成分为主,它们与华中亚热带区系植物关系密切。

GEOGRAPHIC DISTRIBUTION OF THE RARE, ENDANGERED AND PROTECTED PLANTS IN ZHEJIANG AND THEIR CHARACTERISTICS OF FLORA

In this paper, it mainly analyses the distribution types of the 51 genera of rare, endangered and protected plants and their geographic distributions of the 56 species as well as the floristic characteristics in Zhejiang. The results are summarized as follows:1. The fact that there are the major chinese endemic genera and monotypic genera as well as oligotypic genera in this region shows ancientry and relative origin of the flora of the rare, endangered and protected plants in Zhejiang province.2. The distribution types of 51 genera are obviously of temperate nature, but the geographic distributions of 56 species are mainly subtropical floristic elements and they have close relationship with subtropic flora in Central China.
