摘要:
 以甘肃兴隆山青杄群落为对象，分析了其群落特征和种群空间分布格局。在植物区系地理成分上，该群落属的分布类型以温带性质居多。生活型以高位芽植物最多。群落层次分为乔木层、灌木层、草本层和苔藓层，亦有层间植物伴生。除了样地4为聚集分布外，其他3个样地的青杄种群均为均匀分布。造成均匀分布的原因是青杄的生物学特性和林下华西箭竹生长状况共同引起的。不同海拔、不同林型的4个样地的聚集强度大小依次为：样地4>样地2>样地3>样地1。聚集强度的变化表明，种群年龄和苔藓层厚度同样影响空间分布格局。
Abstract:
 Based on the investigation data from 4 sampling plots of Picea wilsonii forest in Xinglongshan Mountian,Gansu Province,this paper analyzed community characteristics of P.wilsonii forest and spatial distribution pattern of the population.The results showed that most genera belonged to temperate biome,and most species were phanerophytes.Vertical structure of P.wilsonii community included tree layer,shrub layer,herbal layer,and moss layer,accompanying with interstratum plants.Except for plot No.4,which was in uniform distribution,the spatial distribution patterns of the populations in other 3 sampling plots were aggregated ones.The causes of uniform distribution were the biological characteristics of P.wilsonii and the growth condition of Fargesia nitida occurring under trees.Aggregation intensities of the 4 plots which were in different altitudes and different forest types were in the order of plot No.4＞ No.2＞No.3＞No.1,indicating that the age of population and moss layer thickness were associated with spatial distribution patterns of P.wilsonii population.
