运用投影寻踪聚类评价方法和GIS空间叠置方法对重庆市北碚区嘉陵江段岸坡的地质灾害危险性进行了评价,研究发现:岸坡稳定性差的面积为18.98%,稳定性较差的面积为37.77%,两者之和占研究区总面积的56.75%;滑坡、泥石流多分布在向斜与背斜的过渡区域、河湾的凹岸和支流汇入处;基于加速遗传法的投影寻踪评价方法可以用于地质灾害研究,确定因子图层权重.
By using projection pursuit clustering method and GIS spatial overlay method, the risk of geological disasters on the bank slope of Jialing River Section in Beibei District of Chongqing was evaluated. The results showed that the area with poor stability was 18.98% and the area with poor stability was 37.77% of the study area, accounting for 56.75% of the total area of the study area. Landslides and debris flow are mostly distributed in the transition area of syncline and anticline, the bank and tributaries of the river bank. Projection pursuit based on accelerated genetic method Evaluation method can be used for geological disaster research, to determine the weight of factor layer.
