| 摘 要： | 本文运用比较频次法和聚集度指标法,研究了长脊冠网蝽若、成虫的空间分布型。研究表明其分布型属负二项分布,分布的基本成份是个体群。林间抽样方法比较结果,平行线取样法精度较高,适用于林间虫情调查。文中分析并计算了林间调查的最适抽样数,列出序贯抽样分析表。

| Abstract: | Spatial distribution patterns for the nymphs and adults of Stephani-tis(S. )sevensoni Drake were measured by Chi-square test of frequeney distribution and eight indexes of aggregation. The results show that the spatial distribution pattern of stephanitis(S. )sevensoni obeys the common negative binomial distribution,the basic component of spatial distribution pattern is colony. The results of five sampling methods show that the method of paralled lines is the best. The theoretical sampling number of forest survey is analysed and calculated, and the sequential analysis is also applied. |
