| 摘 要： | 鼠妇是生态系统中林间落叶的重要分解者,对促进生态系统的物质循环和能量流动有重要作用。应用Taylor的幂法则、Iwaom*-m回归分析法及6个聚集指标,对黄河三角洲地区杨树林地鼠妇的空间分布型和抽样技术做了研究。结果表明,鼠妇呈聚集分布,分布的基本成分是个体群,其聚集性随密度的增加而增大。聚集的原因与鼠妇自身喜欢阴暗潮湿的习性和林地的环境因素有关。运用Iwaom*-m回归中的2个参数α和β值,确定了在不同精度下的理论抽样数及序贯抽样数。

| Abstract: | Sowbugs are important decomposer,feeding on dead wood and leaves.This procession can accelerate material cycling and energy flow in forest ecosystem.In the study,the spatial distribution pattern of sowbugs in poplars forests was analyzed using Taylor's power law,Iwao's distribution function,and six aggregation indices.The results showed that the spatial distribution pattern of sowbug was aggregated,and the basic component of the distribution was individual colony whose aggregation intensity increased with d... |
