摘  要：
对江西省三清山裸子植物区系调查统计结果表明,裸子植物8科、24属、31种,占江西省裸子植物(12科、41属、197种)的66.67%、58.54%和15.74%,占中国裸子植物(12科、49属、293种)的66.67%、48.98%和10.58%,其中自然分布有6科、14属、17种。科分布型以北温带和泛热带分布为主;属分布型以北温带和中国特有成分为主,东亚-北美间断分布和东亚成分也不少;种分布型以东亚和中国特有分布为主,热带亚洲分布也不少。按生态型分,温性针叶树种为主,占总属数的70.97%,暖性针叶树种占22.58%。与黄山、武夷山、天目山、井冈山和庐山裸子植物区系进行比较,并计算了三清山与各山地的相似性以及属种系数,结果表明:6个山地科和属分布型以北温带为主;种以中国特有分布型为主。三清山与五山地在科、属和种级水平上相似性系数及属种系数都很高,但在属种组成上有一定的差异性,最后,对各山地珍稀濒危保护物种进行了归纳统计。

摘  要：
The investigation of gymnosperm flora of Sanqingshan Mountain in Jiangxi Province showed that there are 8 family,24 genera and 31 species,which reached 66.67%,58.54% and 15.74% of the total gymnosperm-family plants in Jiangxi Province respectively,and 66.67%,48.98% and 10.58% of the total gymnosperm-family plants in China respectively.The wild plants are 6 families,14 genera and 17 species among them.The areal type and gymnosperm flora are analyzed.The areal type of family is Pantropic and North temperate primarily;The areal type of genera is endemic to China and North temperate primarily,and East Asia and East Asia to North America have been found also;The areal type of species is endemic to China and East Asia primarily,and Tropical Asia has been found also.According to ecotype,70.97% of the total genera is temperate conifer,22.58% of the total genera is warm conifer.This paper compared the gymnosperm flora of the Huangshan Mountain,Wuyishan Mountain,Tianmushan Mountain,Jinggangshan Mountain,Lushan Mountain and Sanqingshan Mountain,and calculated the comparability coefficients of the plants in five Mountain and Sanqingshan Mountains,and the ratio of genus and species.The result is as follows: the areal type of genera and family is North temperate primarily,the specific areal type is endemic to China primarily,the comparability coefficients of the flora and the ratio of genus and species all are high in the five mountains and Sanqingshan Mountain,but components of genera and species also differ.The rare and endangered plants in six mountains are sorted out statistically.
