广西环江县石灰岩山地广东松林群落学特点的研究

广东松分布范围比较广阔, 生态适应性较强, 主要见于山顶和山脊恶劣的生境中。广西环江县石灰岩山地有小片森林的分布。本文对其群落外貌、结构、种类组成、演替和主要群落类型等, 作了较详尽的分析, 说明它的发展与石灰岩常绿落叶阔叶混交林有一定的联系。广东松是一种优良材用树种, 值得在适宜地区作为造林树种加以发展。

THE STUDY OF THE PHYTOCOENOLOGICAL FEATURES OF PINUS KWDNGTUNGENSIS FOREST IN HUANJIANG COUNTY,GUANGXI

Pinus Kwangtungensis is widely distributed in the subtropics and tropicsto the south of Nanling mountain, it cau grow well both in limestone and in sandstone and shale mountain, mainly oddly occuring in the top and ridge of higher elevations (above 700-1000m.).There is distribution of Pinus kwangtungensis forest of small area in Huanjiang County。This Paper de-als with its phytocoenological features, including community physiognomy, structure, floristic composition, succession and main association etc. It may be seen from mentioned above research information, its formation and development have close relation to limestone mixed evergreen and deciduous broadleaf forest, which is the climax type suited with local environment。Pinus kwangtungensis is an useful timber tree, it may be used as regeneration species of higher elevations in subtropics of Guangxi.
