摘　　要：采用聚集度指标法和回归分析法 ,对思茅松毛虫幼虫在林间的空间格局进行测定 ,并用刀切法对聚集度指标进行估计和检验 ,结果表明 ,思茅松毛虫幼虫在林间呈聚集分布 ,分布的基本成份为个体群。并计算了林间调查的理论抽样数 ,列出序贯抽样分析表。Measured by aggregative index and regressive analysis, and by assessing and checking the aggregative index with Jackknifing, the spatial pattern of larvae of Dendrolimus kikuchii Matsumura fell into the clumped distribution, with individual colony as its component. The optimal sampling number of survey in forest fields was analyzed and calculated, and the sequential sampling analysis was presented.
