摘　　要：根据数理统计的大数原理,建立概率模型对我国地质灾害的分布特征进行研究.首先分析地质灾害在六个行政区的分布特点,然后分析隶属于各行政区的所有省、市和自治区的地质灾害分布特征.结果显示不同类型与不同的区域之间存在着不同程度的强相依性,分布格局明显.According to law of large number in mathematical statistics, a probabilityjnodel is built in this paper to study distribution characteristics of geological hazards in China. At first, authors analyze distribution characteristics of geological hazards in six administrative regions, and then analyze that of geological hazards in all provinces, cities or Autonomous regions affiliated to every administrative region. The results suggest distribution pattern is distinct for there exists strongly dependences between different geological hazards and regions in different degree.
