江西亚热带常绿阔叶林的生活型

笔者以井冈山、云居山、莲花山、庐山、大岗山、新建、永丰等地亲自考察的第一手资料以及有关植被资料,对江西亚热带常绿阔叶林生活型进行研究。亚热带常绿阔叶林均以高位芽植物占优势,比例为60—90％,北、中、南亚热带常绿阔叶林的高位芽植物占的比例分别为60—70％、70—80％、80—90％。随着纬度的降低和生态系统顺向演替,伴随着群落中的高位芽植物比例增加,地上、地面、隐芽植物成分递减。

STUDIES ON THE LIFE FORM OF EVERGREEN BROAD-LEAVED FOREST OF SUBTROPICS IN JIANGXI

Through investigating the vegetation in Yunjushan, Jingangshan,Lian-huashan, Xinjian, Yongfeng and Danggangshan, author the life-form of evergreen broad-leaved forest of subtropics in Jiangxi was analyzed. With the progressive succession of ecological system and the decrease of latitude, phanerophytes get more and more; hemicryptophytes, chamaephytes and therophytes get fewer and fewer. In the northern, central and southern subtropical evergreen broad-leaved forests, the percentage of phanerophytes is 60-70%, 70-80% and 80-90% respectively.
