助地理信息系统空间分析技术和CF法,对该县滑坡各致灾因子进行敏感性分析,获得各因子的敏感性区段。分析表明,岩性、坡度、坡向、起伏度、与河流距离和与主要道路距离是影响该县滑坡发育的主要因子。根据各致灾因子的CF值建立的回归模型进行研究,结果表明所建模型可解释百分之八十的已发滑坡。 Assisted spatial analysis technology and CF method of GIS to analyze the sensitivities of various hazard factors of landslides in the county and get the sensitive sections of each factor. The analysis shows that lithology, slope, aspect, undulation, distance to the river and distance from the main road are the main factors affecting the landslide development in this county. According to the regression model established by the CF value of each hazard, the results show that the model can explain 80% of the developed landslides.
