摘要: 考察了山楂叶螨成螨在树内的三维空间格局及其聚集与扩散的趋势,并用聚块性指标研究了其聚集强度的时序变化。结果表明,在垂直和水平方向,山楂叶螨成螨在树内的空间格局均为聚集型,呈单个个体或小的个体群分布,以下层树冠的聚集强度为最高。根据种群的空间格局,给出了上、中、下3层树冠的数据代换公式。

Abstract: Three-dimensional spatial pattern of hawthorn spider mite adults and its aggregation and dispersion types are observed, and time series dynamics of its aggregation intensity are studied using patchiness index. The results show that all of the spatial pattern of adult mites an apple tree are aggregatively distributed as individuals or small colonies, and the aggregation intensity in lower crown is the highest. Based on spatial pattern of population, data transformation formulae about upper, middle and lower crowns are given.
