摘　　要：采用Taylor幂法则、Iwao线性回归及各种聚集度指标法分析了枣园第三代枣瘿蚊(Contarinia datifoliaJiang)幼虫的空间分布型。结果表明,第三代枣瘿蚊的幼虫在田间符合聚集分布,分布的基本成分为个体群,且个体间相互吸引。并在初步明确枣瘿蚊幼虫分布型的前提下,根据Iwao最适抽样公式得出了理论抽样模型:N=(t^2)/(D^2)((1.9629)/m+0.3801),并计算出不同虫口密度下最适理论调查取样数量及序贯抽样模型。The spatial distribution of Contarinia datifolia Jiang F3 larvae were examined by using various indices of aggregated degree and the regression of straight line （ m＊-- m ） and Taylor method. All indices indicate that the spatial distribution of the larvae in the fields belongs to the aggregated pattern. The larvae occurred as individual groups and the individuals mutually aggregated each other. The suitable sampling quantity model of the different larvae density and the sequential sampling model were presented on the spatial pattern analysis：N=t2/D2（1.9629/m＋0.3801）
