| 摘 要： | 应用聚集度指标法、回归分析法、马占山"重新解释的Taylor幂法则"对雷公藤丽长角巢蛾幼虫种群空间分布格局进行测定。结果表明,雷公藤丽长角巢蛾幼虫在雷公藤样地内呈聚集型分布状态,分布的基本成分为个体群,个体之间相互吸引;用马占山"重新解释的Taylor幂法则"分析得出,雷公藤丽长角巢蛾幼虫的种群类型归属于"聚集度逆密度制约型"。

| Abstract: | Based on aggregation index method,regressive analysis method and Taylor's power law method reinterpreted by MA Zhan-shan,the spatial distribution pattern of Xyrosaria lichneuta larvae was conferred to assemble distribution type in the sample plot of Tripterygium wilfordii,and the basic distribution component was individual population.Within each population,the individuals attracted each other.According to MA Zhan-shan's method,Xyrosaria lichneuta larvae population belonged to "reversed density dependent" type. |
