区域滑坡的研究是近几年滑坡领域的一个研究热点,而对于区域滑坡研究而言,影响因子(环境因子和触发因子)的敏感性分析是其中的一个难点.在基于滑坡历史资料分析的基础上,提出了一种新的较为客观的影响因子的敏感性分析方法,并利用此方法对研究区-四川省雅安市雨城区内的区域滑坡的影响因子进行了敏感性分析.结果表明:此种方法较之其它方法更为客观,能较为真实地反映实际情况.因此该方法可为类似区域滑坡研究提供借鉴.
The research on regional landslides is a hotspot in the field of landslide in recent years, and the sensitivity analysis of the influencing factors (environmental factors and triggers) is a difficult point for the study of regional landslides.Based on the analysis of landslide historical data , A new and more objective method for sensitivity analysis of influencing factors was proposed and the sensitivity analysis of the influencing factors of regional landslides in Yucheng District of Ya’an City in Sichuan Province was conducted by using this method.The results show that The method is more objective than other methods and can reflect the actual situation more accurately, so this method can provide reference for the study of landslides in similar areas.
