摘要
在定量化和空间化模拟分析的基础上,探讨了城市化对传染病传播影响的模型框架。该模型框架是通过人口空间分布表面,集成了元胞自动机土地开发模型、人口预测矩阵模型和元胞自动机传染病模型,在动态的,随机的模拟环境中将城市化与传染病传播结合起来。以英国南安普顿市为研究区,对南安普顿市的“郊区化”对传染病传播的影响进行了动态模拟,场景模拟和定量分析。结果表明:4个模拟预测年期(2001年、2011年、2021年和2031年)的平均传染病例数没有太大的变化,“郊区化”对传染病的传播没有太大影响。但是,“郊区化”中的城市局部的家庭迁移和全市的年轻年龄组的迁移可能会通过在同年份减少平均传染病例数而影响传染病的传播。
This paper presents a modelling framework to model the effect of urbanization on the transmission of infectious disease, which integrates a CA land use development model, population projection matrix model and CA epidemic model by population surface modelling, allowing to analyze its simulation results in a quantitative and spatial way. Its creative feature is combining urbanization, population projection in age-structure with infectious disease transmission in a dynamic, stochastic modelling environment, so it can shed light on providing the relationship between urbanization and infectious disease transmission, which could not be realized by equilibrium or analytical methods. A case study is presented involving modelling influenza transmission in a dynamically evolving city, Southampton, UK. Preliminary results show that the average number of infection cases in years （2001, 2011, 2021 and 2031） has no big difference from each other and suburbanization has very little impact on the infection disease transmission. Moreover, simulation scenario is a useful way to explore the effects of families＇ movements in part of the city and age-group 20-24 moving out of Southampton on infectious disease transmission here. Its results have the possibility to reflect that both the families＇ movements in part of the city and age-group 20-24 moving out of Southampton can influence the infectious disease transmission by decreasing the average number of infection cases in the same year.
