摘　　要：在５～１５年生落叶松人工林内，松瘿小卷蛾幼虫的空间分布型为聚集分布、分布的基本成分是个体群、种群扩散为聚集扩散。在序贯取样中应用Ｉｗａｏ的序贯抽样公式，根据Ｉｗａｏ的方法。按确定最适抽样数。The spatial distribution pattern of Laspeyresia Zebeana (Ratz.) Larvae isaggregative in 5～15 years larch plantations. The basic component of itsdistribution is individual flock. the population diffusing is aggregative. Iwao'sequation was used in sequential sampling. and the optimal sampling number wasdetermined by the equation N=1/D2 [(α + 1)/ x + β- 1].
