| 摘 要： | 小绿叶蝉在苹果园的种群空间分布型用Taylor幂法则,Iwao的m-m回归分析法进行分析,得出的结果均一致,即在小绿叶蝉发生活动期均为聚集分布,且随种群密度的变化,聚集和扩散趋势呈现出一定的规律性。

| Abstract: | The spatial distribution of Empoasca flavescens (Fabricius) population was studied by the means of Iwao's patchiness and Taylor's law.The results showed that the spatial patterns of Empoasca flavescens (Fabricius) within its development period were aggregated. Also,the results realized that Empoasca flavescens (Fabricius) population had the aspect of regular aggregation and dispersion incidence with various investigation date. |
