摘要
应用聚集度指标和回归分析等方法,测定了焦艺夜蛾幼虫的空间格局。结果表明,焦艺夜蛾幼虫在马尾松林内呈聚集型分布,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幂法则分析表明,焦艺夜蛾幼虫的空间格局归属于“聚集度逆密度制约型”。
By use of the aggregation index analyze method, regressive model analyze method and the reinterpreted Taylor＇s power law method, the spatial distribution pattern of Hyssia adusta Draudt larva in pine forest was investigated and analyzed in Wuyishan City, Fujian, May 2006. The results indicated that the reversed density dependent pattern was suitable for this special larva-population of May.
