| 摘 要： | 本文根据地域间突发性地质灾害发生的相似性,将全国区划为9个自然区域;然后依据统计学的大数原理,建立了概率模型分析地质灾害在9个自然区域的分布特点以及隶属于各自然区域的所有省、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。

| Abstract: | The whole country is divided into 9 natural regions on base of Similarity of the abrupt geological hazards happened in different regions.According to law of large number in mathematical statistics,a probability model is built in this paper to study distribution characteristics of geological hazards among 9 natural regions and among all provinces,cities or Autonomous regions affiliated to every natural region.The results suggest distribution pattern is distinct for there exists strongly dependences between different geological hazards and regions in different degree. |
