摘    要:应用地学统计学的原理和方法方法研究了不同时期桃-点叶蝉及草间小黑蛛种群的空间结构和空间相关性。结果表明,不同时期桃-点叶蝉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25.71-37.14m之间,草间小黑蛛种群的拟合并变异函数也表现为球型,呈聚集空间格局,空间变程在25.12-44.06m之间,并与桃-点叶蝉种群在数量和空间上有较强的追随关系,说明草间小黑蛛种群是桃一点叶蝉种群的优势种天敌。

关 键 词:桃-点叶蝉  草间小黑蛛  空间格局  地学统计学研究

Abstract:The spatial construction and distribution of Erythroneura sudra and Erigonidum gramimicola at different periods were investigated with geostatisics. The results showed that the semivariogram of Erythroneura sudra was described by spherical model, indicating an aggregated spatial arrangement. The range was 25.71-37.14 m. The semivariograms of Erigonidum graminicola was fitted by spherical model too, also indicating an aggregated spatial arrangement, and its range was 25.12-44.06 m. The amount and spatial distribution of Erigonidium graminicola was closely related to that of Erythroneura sudra. It reveals that Erigonidium graminicola is the dominant natural enemies influencing the population of Erythroneura sudra.
