应用地学统计学的原理和方法研究油菜角果成熟期桃蚜及萝卜蚜种群的空间结构和空间相关性。结果表明：桃蚜种群半变异函数曲线为球型和指数模型，其空间格局为聚集型，变程范围为0．32—16．43m；萝卜蚜种群半变异函数曲线也为球型和指数模型，呈聚集空间格局，空间变程在0．59～17．39m。采用GS＋对空间分布数据进行插值和模拟，显示桃蚜聚集程度逐渐减小，变程也随之减少；萝卜蚜的聚集程度增加，最终形成一个强聚集中心。

The spatial structure and correlativity of both Myzus persicae and Lipaphis erysimi populations at different period were investigated with the method of geostatistics. The results showed that the semivariogram of Myzus persicae appeared as spherical and exponential type. It indicated that its spatial pattern was an aggregated type with a range from 0.32 to 16.43 m. The semivariogram of Lipaphis erysimi was fitted into spherical and exponential type, that indicating an aggregated spatial arrangement with a range of 0.59 - 17.39m. The simulation distribution maps of M. persicae and L. erysimi populations showed that the Aggregative Intensity of M. persicae and range are gradually cut down and the Aggregative Intensity of L. ery- simi is gradually increased and finally formed a strong aggregative center.
