| 摘 要： | 应用比较频数法 ,结果表明基夜蛾幼虫在林间的空间分布型为 Neyman分布 ,实测χ2 =8.30 7<χ20 .0 5=9.448.根据各种聚集度指标 ,测定结果为幼虫在林间呈聚集分布 .根据各样地 M* 和 x值作线性回归得 M* =0 .1 931 + 1 .40 37x,说明基夜蛾幼虫在林间属聚集分布 ,分布的基本成份是个体群 .将各样地平均密度 x和方差 S2作幂法则得 S2 =1 .5 4 1 6x1.10 98,说明基夜蛾幼虫在一切密度下都是聚集的 ,而且聚集度随着种群密度升高而增加 .同时计算了林间调查的理论抽样数 ,列出了序贯抽样分析表 |

| Abstract: | The methods of comparative frequency distribution was employed to measure the spatial distribution patterns of larva of Kumasia kumaso(Sugi) in Fujian province The results showed that the larva obeyed the Neyman distribution The spatial distribution patterns of the larvae of Kumasia kumaso(Sugi) were measured by the index of aggregation,Taylor power index equation,means of aggregation,M *~m model The results showed that spatial distribution patterns of Kumasia kumaso(Sugi) were aggregate at all density,and the index of aggregation increase with the increase of population density Larvae aggregation possibly were related to the ecological environment What , s more,the optimal sampling number was calculated by Iwao's method,and the sequential sampling number is also analyzed |
| Keywords: | Kumasia kumaso(Sugi) Acidosasa edulis larvae spatial distribution pattern |
