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。
According to the similarities between the emergent geological disasters in different regions, the paper divides the whole country into 9 natural regions. Based on the principle of large number of statistics, this paper sets up a probabilistic model to analyze the distribution characteristics of geological disasters in 9 natural regions, Distribution characteristics of geological disasters in all provinces, municipalities and autonomous regions in all natural regions. The results show that different types and different regions have different degrees of strong dependence, the distribution pattern is obvious.
