摘　　要：采用4种聚集度指标、Taylor幂法则及Iwao的m*-m直线回归法测定了秋大豆豆荚螟幼虫空间分布型。结果表明,秋季大豆豆荚螟在发生量比较大时,田间呈均匀分布;并进而得出了理论抽样数和序贯抽样模型。According to the investigation of EtieUa zinckenella of autumn soybean in field, its spatial distribution was obtained with the methods of aggregated target, power law of Taylor and regressive relation. The quantity of pest occurred was quite big with the pattern of even distribution. Based on this distribution pattern, a suitable sampling number and model of sequential sampling were proposed.
