运用灰色预测模型GM(1,1)对我国心脑血管病的死亡率进行建模拟合和预测分析,为心脑血管病防控工作重点的有效确定及防控措施的合理制定提供科学依据。以全国2003—2012年10年间的心脑血管病死亡率为研究对象,采用灰色预测模型GM(1,1)对2013—2020年的全国心脑血管病死亡率进行预测,利用后验差检验,通过小误差概率p值,方差比c值,误差q值,综合评价模型的预测精度。建模分析的结果表明,全国心脑血管病死亡率呈逐年上升的趋势,其中,心脏病死亡率上升速度较快,而脑血管病的死亡率上升速度相对平缓。灰色系统理论可以很好地运用到死亡率预测分析方面,未来几年我国心脑血管病死亡率仍居高不下,疾病预防与监控部门应做好防治工作,进一步提升我国的医疗卫生水准。
運用灰色預測模型GM(1,1)對我國心腦血管病的死亡率進行建模擬閤和預測分析,為心腦血管病防控工作重點的有效確定及防控措施的閤理製定提供科學依據。以全國2003—2012年10年間的心腦血管病死亡率為研究對象,採用灰色預測模型GM(1,1)對2013—2020年的全國心腦血管病死亡率進行預測,利用後驗差檢驗,通過小誤差概率p值,方差比c值,誤差q值,綜閤評價模型的預測精度。建模分析的結果錶明,全國心腦血管病死亡率呈逐年上升的趨勢,其中,心髒病死亡率上升速度較快,而腦血管病的死亡率上升速度相對平緩。灰色繫統理論可以很好地運用到死亡率預測分析方麵,未來幾年我國心腦血管病死亡率仍居高不下,疾病預防與鑑控部門應做好防治工作,進一步提升我國的醫療衛生水準。

The modeling fitting and prediction analysis on mortality of cardio?cerebrovascular disease in China is proceeded with grey forecasting model GM(1,1),which provides scientific basis to effectively determine the emphasis of prediction and control work,and reasonably formulate the prevention and control measures for cardio?cerebrovascular disease. The mortality of cardio?cerebrovascular disease in China from the year 2003 to 2012 is selected as the research object,and the mortality of cardio?cerebrovascular disease in China from the year 2013 to 2020 is predicted by grey forecasting model GM(1,1). The prediction ac?curacy of the forecasting model is checked by posterior error,and evaluated by small error probability p,variance ratio c,error q comprehensively. Results of modeling analysis show that the mortality of cardio?cerebrovascular disease is increased year by year,and the mortality of heart disease is increased more obviously while the mortality of the cerebrovascular disease is in?creased smoothly. The grey system theory is well applied in mortality forecast and analysis. The mortality of cardio?cerebrovascu?lar disease in China should be remain high in the next few years. Disease prevention and monitoring departments should do bet?ter in prevention and control work to further promote the medical and health level in China.
