利用地统计学方法并结合当地同期的气象资料，研究了云斑天牛（ Batocera horsfieldi）发生的时空动态及其与气象因子之间的关系。结果表明：云斑天牛幼虫在白蜡林（ Fraxinus chinensis）中主要集聚分布在1 m以下的空间（75．0％），且随受害程度增强幼虫在1 m以上空间的分布量会增多；2011—2014年，受害最严重的年份是2013年，各受害林分虫口密度都显著大于其他年份，2014年昆虫分布的空间依赖范围明显变小，说明云斑天牛种群数量在2014有所降低，受害程度有所减轻，这与各年间6—8月份温度与降水的变化有明显的关系。2013—2014年，云斑天牛幼虫的空间聚集点有明显扩散的趋势，不同受害林分南北方向扩散相对一致，都有向北扩散的趋势，而东西向有别，重度危害林向东侧扩散，轻度与中度危害林向西侧扩散。

By geostatistics combined with local meteorological conditions, we investigated the spatial distribution and spatio?tem?poral variations of Batocera horsfieldi ( Hope) in Fraxinus chinensis forest, and illuminated its relationship with correspond?ing climate factors. The larvae preferred to concentrate in an area below 1 m ( about 75%) from the bottom of the trees and increased with increasing damage levels above 1 m. The year of 2013 suffered the worst pest whose population density was significant higher than any other years in all kinds of forests. The distance of spatial dependence of larvae was significantly dropped down in 2014, indicating that the damage level fell down. It could be explained properly by climate conditions from June to August in different years. Scrutinizing the different spatial distribution patterns between two years showed that the spatial concentration location of the insect was changed:the insects spread from south to the north. However, the direc?tion between the west and the east was not clear:the heavy damaged forest spread from the west to the east while the rests were opposite.
