摘　　要：以香格里拉县域内典型的藏族聚居村落——尼西乡汤堆村中村为调查研究区域,在神山和非神山中选取高山松群落进行植被样方调查和比较研究,以探讨藏族神山对当地森林的影响作用。结果表明:神山土壤质地明显比非神山差,而神山的森林群落总物种数(47?36)、物种S impson多样性指数(0.585?0.533)、Sha-non-W iener指数(0.477 5?0.448 2)及P ielou均匀度指数(0.354 4?0.327)均比非神山更高;在森林群落结构对比中,神山中森林群落结构也比非神山更为合理。神山更有利于森林植被的恢复,对森林具有一定的保护作用。The vegetation difference between Tibetan holy mountain and ordinary in Shangri-la county of Yunnan province was studied by choosing Tangdui village of Nixi township in Shangri-la county as study area. Sampling plot survey and comparative study were conducted on Pinus densata communities, with the objective to reveal the effect of holy mountain on local forest. The study results indicated that the texture and characteristics of soil of holy mountain were significant better than that of ordinary mountain. Within the sampling plots, all the study indexes of holy mountain were better than the ordinary mountain, the number of plant species in holy mountain and ordinary mountain were 47 and 36 respectively, the Simpson index were 0. 585 and 0. 533 respectively, the Shanon-Wiener index were 0. 477 5 and 0. 448 2 respectively, the pielou index were 0. 354 4 and 0. 327 respectively. The community structure of holy mountain was also more reasonable than ordinary mountain. It was concluded from this study that Tibetan holy mountain was benefit for the revegetation, and showed obvious protection function on forest.
