Spatial characteristics were analyzed using geo-statistical methods for population of carpenterworm larvae in two woodlands with different damage levels and egg masses in heavily-infested woodland in order to effectively control the insect and to further study the spatial distribution of its population .

为了有效地控制其危害，深入了解种群的空间结构，利用地统计学方法分析了两种受害程度不同的林分内沙棘木蠹蛾幼虫种群和重度受害林分内卵块的空间分布特性。

Analysis of the isotropic variogram indicated that the distance of spatial dependence of the carpenterworm larvae was 7.3 m in the heavily-infested woodland and 87.418m in the lightly-infested one , while the intensity of local spatial continuity was 0.914 and 0.178 , respectively .

根据全方向的变异函数曲线图分析得知：重度受害林分和轻度受害林分内幼虫种群的空间依赖范围分别为7.3m和87.418m，而局部空间连续性强度分别为0.914和0.178。
