| 摘 要： | 利用地统计学原理和方法,对枣园中枣瘿蚊及其天敌草间小黑蛛种群的空间结构和空间相关性进行了研究.结果表明,6月8日、8月27日、10月19日枣树主要生育期阶段,枣瘿蚊种群的半变异函数模型为球形.在林间基本上呈聚集分布,其样点空间依赖性距离分别为26.3、7.8和22.0 m,其空间依赖性程度分别为88.05%、85.77%和87.58%.草间小黑蛛种群的半变异函数也为球形,呈聚集分布,空间依赖距离分别为28.3、22.5和22.2 m,且在该取样尺度下,总变异中分别有90.09%、87.96%和85.72%是由空间依赖性产生的.两者空间依赖关系说明草间小黑蛛对枣瘿蚊有较强的追随作用. |

| Abstract: | With the principles and methodologies of geostatistics,this paper studied the spatial structure and space dependence of Contarinia sp.and its natural enemy Erigonidium graminicola in a jujube orchard at different date.The results indicated that the semivariogram of Contarinia sp.on 8 June,27 August and 19 October could be described by spherical model,showing an aggregated spatial distribution with the ranges of spatial dependence being 26.3,7.8 and 22.0 m,and the degrees of spatial dependence being 88.05%,85.77% and 87.58%,respectively.The semivariogram of Erigonidium graminicola could be also described by spherical model,showing an aggregated distribution with the ranges of spatial dependence being 28.3,22.5 and 22.2 m,and the degrees of spatial dependence being 90.09%,87.96% and 85.72%,respectively.It is suggested that Erigonidium graminicola is the dominant natural enemy against Contarinia sp.population in the examined jujube orchard. |
