Community Structure of Picea wilsonii Forest in Xinglongshan Mountain
摘要
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.关键词
