摘要:

应用聚集度指标法、Iwao 法和Taylor法等对单季稻褐飞虱的空间分布型进行测定检验,结果表明单季稻褐飞虱呈聚集分布,其聚集强度是随着种群密度升高而增加。在此基础上提出了最佳抽样方式、最佳理论抽样数和序贯抽样模型。

Abstract:

we tested the spatial distribution pattern of Nilapavata lugens on the late rice season. The testing method included the aggregated indices method, Iwao method, and Taylor power law method. All of three methods shown that the distribution pattern of Nilapavata lugens is the assemble distribution type. Moreover, the assemble distribution index increased along with the increasing of their population density. Based on the distribution pattern, we proposed the best sampling method, the best theoretical sampling method, and sequential sampling model.
