阳春市崩塌、滑坡地质灾害空间分布与影响因素研究

The Spatial Distribution and Influencing Factors Analysis of Collapse,Landslide Geological Hazards:the Case of Yangchun County

在GIS技术的支持下,结合阳春市崩塌、滑坡地质灾害点的空间分布特征,采用空间统计与相关分析的方法对地质灾害的影响因素进行定量分析,结果表明:影响阳春市崩塌、滑坡地质灾害发生的主控因素是高程、坡度和工程地质岩组,而降雨及人类工程活动则是重要的外在激发因素。这种对地质灾害影响因素进行研究的思路,对于我国其他地质灾害频发的地区同样具备重要的参考及借鉴意义。

With the support of GIS technology,and in combination with the spatial distribution characteristics of collapse,landslide geological disaster points in Yangchun,this paper makes a quantitative analysis of the causing factors of collapse,landslide geological disaster,and concludes that the main control factors of geological disaster in Yangchun are elevation,slope and engineering geological rock group,while rainfall and human engineering activities are important external excitation factors. This study on the influence factors of geological disasters has important reference and significance for other areas in China.
