| 摘 要： | 近年来山体滑坡以及泥石流等自然灾害事故频发,为能够减少灾害的影响,需要对特定区域的土壤稳定性进行调查或评估。传统对于土壤稳定性的评估一般是采用实地调查的方法,这种方法不仅效率低,而且对事故多发地段对于调查人员的安全影响较大。因此论文利用ArcGIS软件,根据DEM数据以及地区矢量图,通过计算坡度或坡向等方法对云阳县张飞庙景区进行土壤稳定性评估。运用该方法能够快速得到张飞庙景区土壤稳定性情况,确定不稳定区域范围,具有较强的实效性和实用性。

| Abstract: | In recent years,natural disasters such as landslides and debris flows occur frequently.In order to reduce the impact of disasters,it is necessary to investigate or evaluate the soil stability in specific areas.Traditionally,the method of field investigation is usually used to evaluate soil stability.This method is not only inefficient,but also has a great impact on the safety of investigators in accident-prone areas.Therefore,this paper uses ArcGIS software to evaluate the soil stability of Zhangfeimiao scenic spot in Yunyang County by calculating slope or slope direction based on DEM data and regional vector map.Using this method,the soil stability of Zhangfeimiao scenic spot can be obtained quickly,and the range of unstable region can be determined.It has strong effectiveness and practicability. |
