| 摘 要： | 本文以中秦岭地区为滑坡易发性评价对象,针对研究区的情况,选取了坡度、起伏度、地貌类型、岩性、土壤侵蚀强度、活动断裂距、地震动参数、地下水类型、多年平均降雨量9个评价因子,建立了研究区滑坡易发性评价的数据库。运用单因子概率比率模型对各因子和滑坡的相关性进行了评价,揭示了该区滑坡灾害类型特点及空间分布规律,明确了中秦岭地区滑坡地质灾害的极高易发、高易发三大聚集地区的位置。

| Abstract: | As a case study,nine indicators are selected for landslide susceptibility evaluation in middle Qinling Mountain: slope,undulation,geomorphologic type,lithology,soil erosion rating,seismic intensity,seismic ground motion parameter,hydro-geological type,and average of annual rainfalls.A database for susceptibility evaluation is built.Model of uni-factor probability ratio is used to evaluate the relativity between the factors and landslides.Research results reveal the characteristics and spatial distribution o... |
