Bài viết So sánh phương pháp phân tích thứ bậc (AHP) và tỷ số tần suất (FR) trong đánh giá tính nhạy cảm với trượt lở đất: Trường hợp nghiên cứu tại huyện Văn Yên, tỉnh Yên Bái trình bày so sánh phương pháp AHP và FR là hai đại diện của hai nhóm định tính và định lượng trong việc đánh giá độ nhạy cảm trượt lở đất thông qua dữ liệu địa không gian của các yếu tố ảnh hưởng. | Journal of Mining and Earth Sciences Vol. 64 Issue 2 2023 79 - 90 79 Comparison analytical hierarchy process AHP and frequency ratio FR method in assessment of landslide susceptibility.

This study aims to compare the Revised 24th Mar. 2023 efectiveness of the Analytical Hierarchy Process AHP and Frequency Accepted 13th Apr. 2023 Ratio FR modeling in mapping susceptibility to landslides with the Keywords support of a Geographic Information System GIS . The study area is Van AHP Yen district in Yen Bai province which experiences a high frequency of Analytical Hierarchy Process landslides annually. Ten factors were used as variables in the model including the lithology map slope aspect plan curvature profile FR curvature topographic wetness index fault network river network road Frequency Ratio network and land cover data. The study used a landslide statistical report Landslide. that including 211 landslide points to create the frequency ratio model while the pairwise comparison method based on expert opinion was used to establish the weights for the AHP method. The results produced a spatial distribution of landslide susceptibility with five levels very low low moderate high and very high. The study used the Area Under the Curve AUC to evaluate the performance of both models. The results indicated that the model using the Frequency Ratio method outperformed the Analytical Hierarchy Process
