摘    要:用负二项参数(k)、扩散系数(C)、丛生指数(I)、CA值、平均拥挤度(m^*)、聚块性指标(m^*/m)等5种聚集度指标判定出祁连山北坡苔藓青海云杉种群的空间分布型趋向于随机分布,再应用Taylor幂法则、Iwao回归方程进行数学拟合,进一步证明祁连山北坡苔藓类青海云杉种群的空间分布型为随机分布。

关 键 词:青海云杉 空间分布 格局 丛生指数 扩散系数

Abstract:The spatial distribution of Picea crassifolia population in north slope of Qilian Mountains is inclined to random pattern after using 5 kinds of aggregate indices,including negative binomial distribution(k),Coefficient of dispersal(C),Index of clumping(I),Cassie R(C_A),mean crowding(m*) and the index of patchiness(m*/m),and it is proved to be right after using Taylor's model and Iwao's regression equation to calculate.
Keywords:Picea crassifolia    spatial distribution   pattern
