摘　　要：云南兰坪县地处青藏高原东南边缘、滇西北横断山脉纵谷地带,是金沙江、澜沧江、怒江“三江并流”世界自然遗产保护区的中心地带,复杂的地质构造及恶劣的自然环境,导致滑坡、崩塌、泥石流等地质灾害发育。地质灾害点一是沿河谷两测分布,尤其是沿大断裂破碎薄弱带分布。兰坪县地质灾害防治可分为搬迁避让和工程治理。Lanping of Yunnan is in the SE margin of Qing-Zang Plateau,longitudinal valley area of cross mountains,the central region of world natural inheritance“3-river parallel flow”.The complicate geological tectonism and bad natural environment result in the geological disaster development of slip,collapse and debris flow,etc.The geological disaster site is distributed along both sides of valley,especially along the fracture weak zone of megafault.The geological disaster prevent-control can be divided into the migration-avoidance and engineering control.
