"非典"給我國社會的發展和人民身體的健康帶來了不可估量的損失,如何進行有效的防治,一直是我國理論專家和實踐工作者普遍關心的問題.該文通過對北京市"非典"病毒的傳播機制的分析,運用系統動力學的理論和方法建立"非典"傳播的系統模型,通過參數隔離措施的變動,模擬分析了北京市"非典"疫情的發展趨勢以及隔離措施對于整個"非典"疫情控制的影響.研究發現,隔離措施對整個"非典"疫情的控制起著關鍵性的作用:隔離強度越大,采取隔離措施的時間越早,累計患病人數就越少,疫情就能越早受到控制.該研究結果可為以后科學防治"非典"及其它流行性傳染病提供理論依據與指導.
SARS has brought an inestimable loss in the development of our society and people's health, and how to prevent and cure it is a problem being concerned about by the theorists and the workers in practice in China. Based on the analysis of spreading characteristics of SARS epidemic in Beijing, the paper uses the theories and methods of system dynamics to set up a system model of the spreading of SARS epidemic. By changing the parameter - - isolation measure, it simulates the development trend of the SARS epidemic in Beijing and the impact of the Isolation Measure on the Control of SARS Epidemic. Through the study, we find that the smaller the isolation strength is and the earlier the isolation measure is taken, the less the total amount of the patients is and the earlier SARS epidemic is controlled. The result provides a theoretical base and guidance to the prevention and cure of SARS and other epidemic infections.
