【摘要】 本文采用7种聚集度指标法测定了鞭角华扁叶蜂蛹的空间分布型。结果表明蛹在柳杉人工林内呈均匀分布,其分布的基本成分是个体群,个体间相互排斥。用抽样调查方法研究表明,平行线短距离跳跃式取样精度最高。本文还应用Iwao’s方法,分析并计算林间调查的最适抽样数。

【Abstract】 The spatial distribution patterns of Chinolyba flagellicornis (F.Smith) were measured by seven indexes of aggregation, with the result that the spati- al distribution pattern of pupa obey uniform distribution, the basic component of spatial distribution pattern being colony. The results of sampling methods show that the method of parallel line of short distance is the best, and the theoretical sampling number for forest survey is also analysed.
