应用地学统计学方法分析了柑橘园主要害螨柑橘全爪螨Panonychus citri(McGregor)种群的空间格局及其动态.结果表明,柑橘全爪螨种群具有空间相关性,变程介于1.10～21.0 m,其半变异函数主要符合高斯模型,表现为聚集分布,其中3月、8月和9月的聚集强度较大;种群空间格局动态显示,4月、10月为该种群的两个发生高峰期,柑橘全爪螨种群数量快速上升扩散.地学统计学方法能够应用于柑橘全爪螨种群的空间格局分析,并有助于对该害螨进行发生预测与控制处理.

The citrus red mite, Panonychus citri (McGregor), is a key pest of citrus. Geostatistic method was applied to study the spatial pattern of citrus red mite population, in citrus orchard by the spatial analysis software Variowin 2.1, The results indicated that the spatial pattern of citrus red mite population can be described by geostatistic method, and the semivariogram of citrus red mite mainly fitted the gauss models with the ranges of 1.1-21.0 m. Citrus red mite population showed an aggregative distribution, and the aggregating intensities were relatively strong in March, August and September. The spatial pattern dynamics showed that two occurrence peaks of citrus red mite population occurred in April and October, specially in October, citrus red mite popula-tion rapidly diffused. March and September were two crucial stages of monitoring and treatment for citrus red mite.
