| 摘 要： | 针对管道沿线的地质灾害分布模式,采用空间统计学中的自相关系数进行研究,并应用该方法评价实际管道地质灾害整体聚集程度,识别局部地质灾害高发聚集区.与传统的管道地质灾害统计分析方法相比,自相关系数基于空间位置进行属性关联关系分析,能够在总体和局部两个层面量化计算地质灾害的空间聚集程度,其计算结果易于排序使用,可以为管道地质...

| Abstract: | Based on spatial statistics,the paper uses spatial autocorrelation to make a study of the spatial distribution pattern of geological hazards along the pipeline,and then applies this method in practice to identify hot spots with geological hazards along the pipeline.Compared with traditional statistic method concerning geological hazards,this method can quantify the overall and local levels of spatial aggregation degree of geological disasters,which takes spatial location into account when it is used to anal... |
