Studies on spatial heteroplasmy of Saperda Papulnea L. population from different directions indicated that the model of semivariogram of eggs, larvae and adults in four directions are the same, but spatial dependent range are different, belonging to geometrical anisotropy. They had stronger continuity in the direction of 0° and 45° than the other two directions.
对不同方向上青杨天牛种群空间异质性研究表明：天牛卵、幼虫和成虫在四个方向上的半变异函数拟合的模型相同，但空间依赖范围却不同，属几何性的各向异性。

The spatial patterns of eggs, larvae and adults of Saperda Papulnea L. in three different types of poplar forests in Jinshatan forest centre, Datong Poplars Institute were studied by using geostatistics tools. Geostatistics allows the usage of quantity and location information simultaneously to qualify the spatial pattern of insect population.
