| 摘 要： | 应用多个聚集度指标和Iwao，Taylor等回归分析方法，对急尖长苞冷杉球果小卷蛾幼虫的空间分布型进行研究，结果表明：其空间分布型为聚集分布；用Blackith提出的“聚集均数”法对聚集原因进行分析，急尖长苞冷杉球果小卷蛾幼虫的聚集现象是由环境因素引起的；在回归分析检验中，以兰星平的La-m回归模型拟合效果最佳．

| Abstract: | The spatial distribution pattern of Blastesthia sp. larvae was studied by means of multiple aggregation indices, and Iwao, Taylor regression analysis methods. The results showed that the spatial distribution pattern of the larvae belonged to the aggregation distribution. In addition, the aggregation average method by Blackith was applied to analyze the aggregation reasons of Blastesthia sp.. The spatial distribution pattern of Blastesthia sp. was positively related to its environmental factors. It was proven by the regression analyses that the La- m regression model had the best simulation effect. |
