摘要(Abstract):

对短毛切梢小蠹蛀干期成虫在思茅松树干分布情况进行调查,并对其空间分布型进行分析,聚集度指标测定值及回归分析结果表明短毛切梢小蠹蛀干期成虫空间分布型为聚集分布;建立了树干各方位虫口密度与样地平均虫口密度回归方程,确定了最适抽样部位为树干南面;建立了最适抽样表并制定了序贯抽样方案,确定了不同允许误差时的最大抽样量。
Survey was made of the density of Tomicus brevipilosus(Eggers) in trunk.The aggregated indices and regression analyses showed that the spatial distribution patterns of Tomicus brevipilosus(Eggers) was a aggregated distribution.The regression equation was established based on different position population density in trunk and sample average population density,and the best sampling position was the south of trunk.At the same time,the best sampling table,sequential sampling plan and the maximum sampling amount were determined.
