| 摘 要： | 春尺蠖是我国中西部地区严重的森林果树害虫,其空间格局的理论研究是种群控制的重要基础。应用地质统计学的半方差函数分析了春尺蠖成虫、卵块和一龄幼虫的空间结构。结果为:春尺蠖成虫、卵块和一龄幼虫种群均为聚集分布,空间相关范围分别是:49m,18m,14m, 它们的聚集强度也有区别,而且存在各向异性。最后采用普通克里格方法空间插值模拟了春尺蠖成虫、卵块和一龄幼虫种群分布状况,取得了较好效果。

| Abstract: | Apocheima cineraius Erschoff is serious pest in forest and fruit orchard in Midwest of China. Spatial patern theoretics of Apocheima cineraius Erschoff population is important foundation of population control.The Apocheima cineraius Erschoff adults and egg masses and 1st larvae population spatial structure were analyzed with semivariogram method of geostatistics, the results as follows:The Apocheima cineraius Erschoff adults and egg masses and 1st larvae population are all aggregated distribution, and the rang is 49m,18m and 14m,but they have different aggregating intensity and anisotropy.The simulation distribution maps of Apocheima cineraius Erschoff adults and egg masses and 1st larvae population which was interpolated by Ordinary Kriging, showed good effect. |
