摘　　要：应用聚集度指标法、回归分析法、零频率方法对松墨天牛幼虫的空间格局进行测定 .结果表明 ,松墨天牛幼虫在松林中呈聚集分布 ,分布的基本成分为个体群 .用零频率方法分析得 ,松墨天牛种群类型为“聚集度零频率制约型”,并确定了林间调查的理论抽样数和简单序贯抽样分析表 .Measured by clump intensity index,regressive analysis method and zero frequency method,the spatial pattern of the larvae of Monochamus alternatus is conferred to assemble distribution in pine forest,By zero frequency method,Monochamus alternatus population was 'zero frequency dependent'.The optimal sampling number of forest survey was analyzed and calculated,and the sequential sampling analysis was presented.
