应用对分法和样条法判定昆虫种群空间分布型

Application of the Half-half and Spline Methods to Analyse of Insect Population Distribution Patterns

本文提出了判定昆虫种群空间分布型的样条法及对分法,并以马尾松毛虫为例进行了计算和分析;用模拟及实例说明了样条法和对分法判断分布型的依据。该方法能判断昆虫种群的空间分布型和聚集块的位置、大小及聚集程度;与已有的分布型指数相比,更能准确反映昆虫种群在空间的分布特征。

The half-half and spline methods were applicated to analyse the population spatial distribution patterns of the Pine Caterpillar. The two methods can not only be used to test the spatial patterns, but also determine the lacation and size of clump.
