| 摘 要： | 根据研究区的基本情况,选择坡度、坡向、地层岩性、距断层距离、降雨、土地利用等6个评价因子,采用滑坡灾害易发性评价的GIS与AHP耦合模型进行戛洒镇滑坡灾害易发性评价,并将滑坡灾害分为极高、高、中、低和极低易发区5个区域进行了滑坡灾害易发性评价结果分析,以期为后期的小流域滑坡风险评估研究服务。

| Abstract: | According to the basic situation of the research region,six evaluation factors,including slope,aspect of slope,formation lithology,distance from the fault,rainfall and land use type were selected to evaluate the landslide susceptibility with GIS and AHP in Jiasa Town.The resulting susceptibility map showed five classes of landslide susceptibility,i.e.extremely high,high,moderate,low and extremely low.The landslide susceptibility evaluation results will be useful for later watershed landslide risk assessment... |
