结合评价区实际,选取地貌类型、坡度、地层岩性、降雨、地震作为影响滑坡灾害的评价因子,以汶川地震最新研究成果为依据,在断层两侧设定不同缓冲区范围,运用层次分析法确定各因子权重,利用GIS空间分析功能,实现评价区滑坡危险性区划.结果表明滑坡灾害高发区主要集中在龙羊峡库区右岸高陡岸坡地带、循化-群科盆地两侧的低山丘陵区.与实际调查结果基本相吻合,可为今后区内滑坡灾害的预测及预防提供科学参考.

According to the real situation of the research region, we select physiognomy, slope, lithology, rainfall and earthquake as the assessment factors, use the newest results based on the Wenchuan earthquake, set two different ranges in both sides of buffer, define the weight coefficient of each factor with the AHP method, realize the risk demarcation for assessment of research region by the spatial analysis function of GIS.The research result shows the high occurrence area of landslide are mainly in the district of abrupt slope on the right side of the Longyangxia Gorge and in the hilly district on the both sides of Xunhua-Qunke basin, which is in accordance with the result of investigation and can be the reference for the following hazard treatment.
