摘　　要：系统调查三叶草草坪,采用聚集度指标I、wao的m.—m回归分析方法,研究了黑盲蝽种群空间分布格局,结果表明:中黑盲蝽种群在三叶草坪上呈聚集分布,聚集原因是由中黑盲蝽本身的行为和环境因素共同引起的。在此基础上,应用Iwao法提出了在一定精度水平下最佳理论抽样数和序贯抽样模型。Based on the investigation of white dutch clover lawn, the spatial distribution pattern of Adelphocoris suturalis Jackson population was aggregatire distribution through the analysis of the method of the aggregated index and Iwao＇ s law. The reason resulting in this result was determined by both Adelphocoris suturalis themselves and environmental factors. And also the suitable sample size and Iwao＇ s model of sequential sampling were proposed for a certain precise level.
