| 摘 要： | 对北京地区红脂大小蠹Dendroctonus valens LeConte空间分布型进行了研究。结果表明红脂大小蠹成聚集分布,其聚集原因是由红脂大小蠹本身的聚集行为或聚集行为与环境的异质性共同作用引起。同时,应用Iwao统计方法,提出了最适理论抽样数和最佳序贯抽样模型。

| Abstract: | The spatial distribution pattern of Dendroctonus valens（LeConte） was investigated in Beijing.The results indicate that spatial distribution was aggregated,probably because D.valens has an innate tendency to aggregate,or because of a combination of this and environmental heterogeneity.Using Iwao＇s statistical methods,models to determine the optimal theoretical sampling number and the optimal sequential sampling number are presented. |
