摘要
本文采用Moore I指标、Lloyd m*/m指标、CA指标、扩散系数C、负二项分布中的K等指标进行聚集度检验。结果表明,环斑猛猎蝽成虫种群趋于聚集分布。
The indexes of I- value, M^*/M - value, CA - value, Diffusive coefficient and K- value were applied to test aggregation degree of the Sphedanolestes irapressicollis population. The results suggested that the adult population tended to be an aggregative distribution pattern.
