| 摘 要： | 概述了地统计学在昆虫种群时空动态分析中的基本方法，应用该方法分析了省通州市和安徽省凤阳县稻纵卷叶螟２３个各世代种群时间格局的结构特征和自相关性，并对历年各世代的种群数量进行了模拟估计。结果表明：种群每世代的累计蛾量和高峰日蛾量在一定世代间隔内均存在着自相关性，当世代间隔超过一定距离时表现为相互独立。两地区种群世代间的影响范围和作用程度的大小存在差异。

| Abstract: | The basic techniques of geostatistics applied in analysing spatial and temporal population dynamics were outlined in this paper. These techniques were used to analyse the temporal pattern and autocorrelation of rice leaf roller population for each generation over 23 years in Tongzhou City, Jiangsu Province and Fengyang County, Anhui Province. The amount of the moth population was estimated and the dynamics of that was simulated. The moth accumulation of each generation and the moth count of each generation in highest peak date indicated autocorrelation within some generation intervals, while the moth population had independence beyond other generation interval. The range and degree of autocorrelation between two sites showed difference. In Tongzhou City, the population showed significant autocorrelation within 8 generation interval, and the autocorrelation arrived at strongest degree when the generation interval was less than 3 4. The moth count of the highest peak date indicated autocorrelation within 9 generation interval, and the autocorrelation reached strongest degree when the generation interval was less than 4 generation. The application of geostatistics to the spatial and temporal dynamics of insect population, migratory and forecast of insect were also discussed. |
