武都地区,位于西秦岭陇南山地,是甘肃省泥石流最发育的一个地区。泥石流主要分布在迭部县以东的白龙江中下游及其支流岷江、北峪河和白水江流域的岷县、宕昌县、武都县和文县境内的河谷沿岸地带;在武都至成县和康县之间的部分西汉水流域,也有泥石流分布。其中以中部的白龙江中下游沿岸泥石流最为发育,分布范围广,规模大,活动频繁,危害严重。由于历史的和近期的人为活动的消极影响,生态环境不断破坏,泥石流日趋严重,给武都地区的工农业生产、交通运输和人民的生命财产造成了极大危害。
Wudu area, located in Longnan Mountain West Qinling, Gansu Province is the most developed area of a debris flow.
