中国松科植物的分布型和区系分析

简介松科研究的新进展,根据新近资料划分中国松科植物10属95种的分布型和进行区系分析,结果是北温带分布4属,东亚-北美间断分布2属,中国特有3属和越南-华南分布1属。25个种分布型分属于欧亚温带、东亚和亚洲热带3个植物区域。比较详细分析其4点主要特征;分布的区域差异和不平衡,高的特有性,间断分布和替代分布等。

THE DISTRITUTION PATTERNS AND FLORISTIC ANALYSIS OF FAMILY PINACEAE OF CHINA

In view of the new advance of research on family Pinaceae and according to the new materials,Chinese plants of Pinaceae containing 10 genera and 95 species are classified into 4 distriution genera-patterns and 25 distribution species-patterns. That is 4 genera North Temperate paterns, 2 genera East Asia and North America disjunction, 3 genera endemic to China and 1 genus Vietnam to South China. The 25 species-patterns belong to respectively the 3 floristic kingdoms(or subkingdoms)of Eurasian Temperate, Malesian, and mainly to East Asiatic. Their characteristics through floristic analysis are mainly distributed in Sino-Himalayan forest sutkingdom and Himalaya-Hengduan mountain region being the distribution and differentiation center, a lot of vicarious distritutions, discontinuous or scattered distritutions as well as some relict distritutions because of the results of environmental change and geographical segregation. These materials and research results may be provided a reference for the research on biodiversity and plant geography of Pinaceae and etc.
