摘　　要：利用C4.5决策树分类方法,定量分析空气污染引发呼吸系统疾病的主要危险因素,生成按性别、年龄分组的分类器模型,探索基于分类模型的定量分析方法,计算9组人群中各自危险因素对呼吸系统疾病的作用程度。该方法能有针对性地分析不同人群的危险因素,为呼吸系统疾病的预防和控制提供依据,也可应用于其他疾病危险因素的分析。A model of classification techniques was established according to the sex and age by quantitative analy-sis of the risk factors for air popplution-induced respiratory diseases using the C4 .5 decision-making tree classifi-cation.The classification-based quantitative analysis was studied.The role of risk factors for respiratory diseases in 9 groups of people was assayed .This method can be used to analyze the risk factors for both respiratory diseases and other diseases in different populations, and can thus provide the evidence for their prevention and control.
