| 摘 要： | 滑坡灾害是天水盆地最严重的地质灾害.本文基于已有的灾害数据,利用GIS叠加分析的结果作为滑坡灾害点的属性特征,与灾害点的核密度分析结果建立关联规则,找出高风险滑坡区域与相关属性特征的关联关系.结果表明:天水盆地的滑坡灾害与降水条件、地层岩性以及地形坡度有较强的关联关系.

| Abstract: | The landslide disaster is the most serious geological disaster in Tianshui Basin.Based on the existing disaster data,this paper uses the results of GIS superposition analysis as the attribute characteristics of landslide disaster points,establishes association rules with the Kernel density analysis results,and discovers the correlation between the high risk areas of landslide and relevant attribute characteristics.The results show that the landslide disaster in Tianshui Basin is closely related to the precipitation conditions,lithology of strata and the slope of topography. |
