| 摘 要： | 应用地理统计学的原理和方法研究了不同时期麦二叉蚜及蚜茧峰种群的空间结构的空间相关性。结果表明，不同时期麦二叉蚜种群的半变异函数曲线皆为球型，其空间格局为聚集型，变程在21-61cm之间；蚜茧蜂种群的拟合半变民间函数曲线也表现为球型，呈聚集空间格局，空间变程在36-55cm之间，并与麦二叉蚜种群在数量和空间上有较强的追随关系，说明蚜茧蜂种群是麦二叉蚜种群的优势种天敌。

| Abstract: | The spatial construction and correlation of Schizaphis granarium and Aphidius sp.at different stages were investigated using geostatistical method. The results showed that the semivariogram of S.granarium was described by a spherical model,and indicated an aggregated special pattern ranging from 21 to 61cm. The semivariogram of Aphidius sp.could be also well described by spherical model, and indicated an aggregated spatial pattern ranging from 36 to 55cm.The amount and spatial distribution of Aphidius sp. were closely related to those of Schizaphis granarium,which reveals that Aphidius sp. was the dominant natural enemies influencing the population of S. granarium. |
