摘要:
以西藏地区370个灌木林标准地调查数据为基础,计算了包括负二项式K值、方差/均值比率t值、丛生指标、平均拥挤指数、聚块性指标、扩散指标、格林指数和Cassic指标,定量测度了各标准地内种群的分布格局类型及集聚强度,分析了西藏灌木种群分布格局随海拔和坡度的变化特征。研究结果表明,1.西藏优势灌木种群分布格局包括集群分布和随机分布两种,其中,随机分布占60%;2.随着海拔及坡度的增加,西藏灌木种群均呈现由集群分布向随机分布变化的趋势,且大部分地区的灌木种群呈随机分布。
Abstract:
Based on the inventory of 370 sample plots covering 33 counties in Tibet which belong to 7 districts, the population distribution patterns and cluster intensity were analyzed. The indexes including negative binomial parameter, ttest of v/m ratio, clumping index, mean crowing index, patchiness index, Morisita index, Green's index and Cassie index were calculated. Meanwhile, the population distribution patterns of variation along with altitude and slope were discussed. The results showed:(1)Clump and random were the two distribution patterns of dominant shrub population in Tibet.(2)the population distribution pattern changed from clump to random along with altitude and slope increasing.
