摘　　要：云斑天牛是我国重要林业蛀干害虫,防治困难,为做好危害杨树云斑天牛种群的防治工作,利用地统计学方法,对云斑天牛种群的空间分布进行了分析。结果表明,云斑天牛的4个危害调查指标刻槽、粪孔、羽化孔和蛀孔的半变函数模型和半变函数参数存在差异,刻槽和排粪孔的拟合模型为高斯模型,羽化孔和蛀孔的拟合模型为指数模型,但其指明的空间分布型均为聚集分布。因此,危害杨树云斑天牛种群的卵、幼虫和成虫(蛹)均呈聚集分布。Batocera lineolatais an important wood-borer pest in China,and it is difficult to control.In the paper,the spatial distribution patterns for B.lineolata population in poplars are analysed with geostatistical methods in order to provide conference for better control.It is showed that there are some differences on the semi-variogram models and parameters of four investigation indexes,including incisions,frass holes,emergence holes,and bored holes of B.lineolata.Both of the semi-variogram curve models of incisions and frass holes are Gauss models,and both of the models of emergence holes and bored holes are exponential models.The spatial distribution patterns of the B.lineolataincisions,frass holes,emergence holes,and bored holes are all aggregated.Therefore,egg,larva and adult(pupa)of B.lineolatapopulation in poplars are all aggregated distribution.
