摘  要：
根据祁连山林区青海云杉群落16块样地256个样方的调查结果,对青海云杉群落的频度分布、层片结构、种群结构和动态进行了研究,结果表明:青海云杉群落频度分布表现为A>BD=E,群落具有分化和演替的趋势;群落季相与气候季节性变化相吻合,反映出群落对祁连山环境的适应性;受青藏高原寒冷气候的影响,生活型以地面芽植物占优势,具有寒温性针叶林的特征;群落结构基本合理,青海云杉呈稳定型种群。不同林型的种群结构和动态都存在较大的差异。

摘  要：
Based on the data collected from the 16 sampling plots and 256 sampling squadnats in Picea classifolia community at Qilian Mountains forest area in Gansu Province,this paper analyzed the frequency distribution,synusia structure,and dynamic of Picea ctassifolia community.The results showed that the frequency distributions were A>BD=E,the community had the trends to succession and differentiation,community aspection and climate seasonality change were identical with each other,indicating that the community has adapted Qilian Mountains environment.Effected by cold weather of Qinghai-Tibet Platean,Hemicrypotophyte was dominant in life form and had characteristics of type clod-warm coniferous forests.The community structure was basically reasonable and Picea classifolia population was a steady one.Different forest types exhibrted significant different structures and dynamics.
