摘　　要：１９９３年在黑龙江省大庆市红旗林场对柳蛎蚧种群的空间分布型进行了研究，采用了频次比较χ２检验的方法和若干种聚集度指标的方法测定柳蛎蚧种群的空间分布型。研究结果：柳蛎蚧种群基本上符合二项分布和Ｎｅｙｍａｎ分布；根据聚集度指标的测定，柳蛎蚧种群符合聚集分布。The spacial distribution pattern of Lepidosaphes salicina was investigated in the Hongqi Forest Farm, Daqing City, Heilongjiang Province In 1993. The spacial distribution pattern of L.salicina population was determined by frequency comparative χ2 test and several indices of aggregation. Results indicated that the population of L.salicina fitted basically the negative biomial distribution and Neyman distribution.Tests with indices of aggregation dimonstrated that the population of L. salicina fitted the aggregation distribution.
