摘要
利用现场调查积累的数据,通过理论分布的拟和、Taylor方程拟和分维分析等方法研究刺扰伊蚊、刺蜇伊蚊、致倦库蚊、三带喙库蚊和不显库蠓等5种蚊、蠓等吸血双翅昆虫自然种群的抽样分布,为防治工作提供理论指导。模拟结果显示,上述5种吸血双翅昆虫的种群抽样分布均满足负二项理论模型,且样本均值和方差间的关系很好地符合Taylor方程,结果表明种群的密度以及样方的测度,对抽样分布有一定的影响。在本文的研究基础上提出了一组关于种群分布理论模型的积分方程。
To built the theoretical bases for controlling Aedes vexans, Aedes punctor, Culex quinquefasciatus, Culex tritaeniorhychus and Culicoides obseletus, investigating the sampling distributions of their natural populations was conducted. The data used here were collected during field work in the past. The fits of theoretical distribution models and Taylor equation as well as fractal analysis were employed in the studies. The results showed that population sampling distributions of all the five species obeyed Negative Binomial model, and the relationship between mean and variance of the samples met Taylor＇s equation well. We could concluded that the sampling distributions of population were affected by both the density and sampling scale of population. A group of integral equation for describing the theoretical distribution of the population was proposed based on this analysis.
