摘　　要：白豆杉Pseudotaxus chienii是国家一级保护植物,也是珍稀濒危植物.本文分析、研究了江西白豆杉地理分布以及井冈山白豆杉群落的特征,结果表明:(Ⅰ)白豆杉在江西主要分布于三清山、井冈山、武功山、遂川南风面、上犹五指峰、德兴、玉山等山区的海拔1 000 m以上的山顶、悬崖或陡坡天然林中;呈现出"微间断分布"的特点;(Ⅱ)白豆杉多分布于高海拔、低温、高湿的山顶矮林地貌,其生物学习性为耐寒喜湿,并且群落结构单一,常混生或伴生于亚热带阔叶林或针叶阔叶混交林中;(Ⅲ)井冈山的白豆杉群落年龄结构为稳定型,具自我维持、发展的生态系统机制,保护策略以就地保护为主,减少人工干扰.Pseudotaxus chienii is rare species and National protected plants in China. This paper studied the geographical distribution of Pseudotaxus chienii in Jiangxi, and investigated an important Community named ＂Community of Pseudotaxus chienii in Mount Jinggang＂. The results show that： （Ⅰ）Jiangxi Pseudotaxus chienii mainly distributed in the areas that belong to forest of 1000 metres above sea level in Mount Sanqing, Jinggangshan Mountain, wugong mountain, Nanfengmian of Suichuan. Five fingers peak of Shangyou, Dexing, Yushan. And also possess the characteristic called ＂micro discontinuous distribution pattern. ＂（Ⅱ）Pseudotaxus chienii are mainly distributed in high altitude, low temperature and high humidity elfin forest landscape. It not only has biological characteristics that are is cold-resistant and hygrophilous, but also the community structure is single and mixed in accompanied by subtropical broad - leaved or coniferous broad-leaved mixed forests. （Ⅲ）The age structure of the Community of Pseudotaxus chienii in Mount Jinggang is stable. It has certain development potential and needed the methods of protected on site and reduce human interference.
