摘　　要：应用扩散系数等 6种指数法测定了红脂大小蠹成虫侵入孔的空间分布型。结果表明 ,红脂大小蠹成虫侵入孔的空间分布型呈聚集分布 ,分布的基本成分是个体群 ,扩散蔓延规律为聚集型扩散。聚集的原因分析表明 ,该虫的聚集是由某些环境因素所致 ,如食物等。Space distribution of entering tree hole of Dendroctonus vales imago was measured by diffusion coefficient (one of six indexes).The results showed that harming hole of Dendroctonus vales imago appeared gathering in tree stem ,every hole is produced by the only one imago,some environment factors such as diet could cause the imago gathering behavior.
