浙江龙王山植物区系与其邻近地区植物区系关系的研究

Studies on the floristic relationships between the longwangshan mountain in ZheJiang and its adjacent regions

本文通过对龙王山植物区系成分的统计,并在此基础上进行龙王山与邻近地区植物区系之间共有种的统计和分析,以及与华东地区诸山植物区系之间相似性系数的统计和分析,得出如下结论:1.龙王山与华东区系的关系最为密切,其次为华中区系,再次依次为华南、西南、华北及东北区系。2.龙王山与我国台湾、日本植物区系关系密切。3.龙王山与华东地区诸山的关系都相当密切,其密切程度依次为西天日山、黄山、庐山、大别山(天堂寨)、九龙山和武夷山。4.在中国植物区系分区上,龙王山应属于华东区。

In this paper,systematic researches on the floristic compenent and floristic relationships between Longwangshan Mt. and its adjacent regions are conducted. By means of constractive analysis of the floristic elements and the shared species between Longwangshan Mt. and its adjacent floristic regions, the author believes that: 1. on the regionalization of Chinese flora,the flora of Longwangshan Mt. should comprise a portion of those of East China. 2. The flora of Longwangshan Mt. is closest to East China,in floristic affinities,next to Central China,thirdly to South China, fourthly to Southwest China and fifthly to North & Northeast China. 3. The flora of Longwangshan Mt. is closely related to those of Taiwan and Japan. 4. The floristic relations between Longwangshan Mt. and the adjacent mountains in East China is very close, from much closer to little closer,the sequence is West tianmushan, Huang-shan,Lushan, Dabieshan, Jiulongshan and Wuyishan. There is no distinct line in these mountains.
