摘要: 采用地统计学原理和方法,拟合了不同时期烟蚜种群及其捕食性天敌草间小黑蛛种群的空间结构模型,分析了其空间关系.结果表明,不同时期烟蚜种群的空间结构模型均为球型,空间格局呈聚集型分布,空间相关距离在2.0252~4.1495 m之间,异质系数为10 281.36~300 216.30,空间依赖程度为12 176.81~303 433.70;不同时期草间小黑蛛种群的空间结构模型也均为球型,空间格局呈聚集型分布,空间相关距离在3.7328~4.8983 m之间,异质系数为1.4482~4.4134,空间依赖程度为1.6941~5.8167.该结果和方法可用于监测烟田目标害虫的时空格局动态.

Abstract: In this paper,the spatial construction models of populations M. persicae and its predatory natural enemy E. graminicola during different periods were simulated by geostatistics,and their spatial relationships were analyzed.The spatial structure of M. persicae population was described by spherical model,showing an aggregated spatial arrangement.Its spatial dependence was 2.0252~4.1495 m,heterogeneity degree was 10 281.36~ 300 216.30, and sample variance was 12 176.81~303 433.70.The spatial structure of E. graminicola population was also simulated by spherical model,showing an aggregated spatial arrangement.Its spatial dependence was 3.7328~4.8983 m,heterogeneity degree was 1.4482~4.4134,and sample variance was 1.6941~5.8167.The results and methods could be applied to monitor the temporal and spatial dynamics of target insect pest population in tobacco field,and provide scientific basis for ecological control.
