利用地学统计学的原理和方法分析了李园桃蚜种群和草间小黑蛛种群的空间结构和时间相关性.结果表明,桃蚜种群6月27日和11月22日此两次的半变异函数拟合模型为直线,表明此两次两种空间分布为均匀分布或随机分布,其余9次半变异函数拟合模型均为球形,表明此9次李园桃蚜种群的空间分布是聚集分布,变程RSD(m)为4.173903～34.7837.草间小黑蛛空间格局5月21日、5月31日及10月19日、11月22日4次半变异函数拟合模型为直线,表明此4次种群的空间分布为均匀分布或随机分布,其余8次半变异函数拟合模型均为球形,表明此8次李园草间小黑蛛种群的空间分布是聚集分布,变程RSD(m)为2.3169～42.00711,表明草间小黑蛛种群对桃蚜种群在空间位置上具有追随关系,对其种群数量的控制有较大作用.
Using the principle and method of geostatistics, the spatial structure and temporal correlation of Myzus persicae populations and Myzus persicae populations were analyzed.The results showed that the semivariogram of the Myzus persicae populations on June 27 and November 22 The fitted model is a straight line, indicating that the two spatial distributions are uniformly distributed or randomly distributed, and the other nine semivariogram fitting models are spherical, indicating that the spatial distribution of the population of Myzus persicae in the nine times is aggregative distribution. RSD (m) was 4.173903 ~ 34.7837. Spatial pattern of grasshopper black spider on May 21, May 31 and October 19, November 22, four semi-variogram fitting model was a straight line, indicating that the four The spatial distribution of the population was uniform or random distribution, and the other eight semi-variogram fitting models were spherical, indicating that the spatial distribution of the eight black Liriodendron populations was aggregated distribution with RSD (m) 2.3169 ~ 42.00711, which indicated that there was a follow-up relationship between the populations of Myzus persicae in space and the control of their population size.
