贵阳黔灵山华山松群落分布及特征初步研究

Research on the characteristics and distribution of Pinus armandii forest community on the Qianling Mountains

对黔灵山华山松的分布范围、群落特征和生境作了初步调查分析。结果表明：华山松主要分布于公园东门附近的小山、关刀岩、檀山和杖钵峰等，大罗岭少有分布，狮子岩、象王岭和白象岭则鲜见分布。分布区主要为黄壤类酸性土，伴生树种主要为马尾松。典型组成是：华山松-马尾松-油茶群落。华山松幼树出现较大断层，高度在1～5m之间仅发现1棵幼树，主要原因可能与黔灵山郁闭度在0．7-0．9以上及病虫害等有关，而郁闭度高可能是主要原因，具体原因值得深入研究。

A preliminary examination and analysis have been made on the distribution scope , community characteristics and habitat of Pinus armandii on the Qianling mountain. The results indicate that Pinus armandii mainly distributes nearby the hills of the park＇ s east gate, namely, the Guandao crag, Mount Tan, Zhangbo peak, etc. The Daluo range has less distribution. The Shizi crag, Xiangwang peak and Baixiang peak have no distribution. The distribution area is mainly the acid yellow soil, and associated species is mainly masson＇ s pine. The model compositions are Pinus armandii, masson＇ s pine and Camellia oleifera community. The young Pinus armandii trees sapling distribution appears a bigger fault, only one is discovered at the height of 1 -5m. The main reasons are possiblyrelated to canopy density of Qianling which lies above 0.7 - 0.9 and plant disease. But height of canopy density is the main possible reason. The concrete reason is worth a deeper study.
