| 摘 要： | 根据对寒地稻田内水稻负泥虫幼虫及卵的调查，计算了５种聚集度指标，并进行了Ｉｗａｏ回归分析和Ｔａｙｌｏｒ幂的法则分析，结果表明：该虫幼虫及卵在田间均为聚信分布，聚集强度对种群密度具有依赖性，环境条件是引起虫体聚集的主要因素，幼虫在田间在分布单位为个体群，卵为单一个体，同时提出了理论抽样数的公式。

| Abstract: | Based on the preliminary survey of Oulema oryzae (Kuwayama) several methods were used to test the spatial distribution pattetns in rice fields of cold. The results showed that the spatial distribution patterns are aggregated in larvae and eggs, and the level of aggregation was relied on the density of population. The main reason of aggregation was the environment and the distribution unit of larvae were the group, but the distribution unit of eggs were individuality; the formulae of sampling for larvae and eggs were established. |
