云南石屏县地质灾害特征及成灾规律研究

云南石屏县地处云南高原南缘,县域总体地势北高南低,倾向红河河谷,地质构造复杂,地质环境条件比较脆弱。经实地调查,其地质灾害的类型主要有滑坡、崩塌和泥石流,这些地质灾害点大多沿断裂带集中分布。石屏县山高坡陡的地形地貌是地质灾害发生的重要控制因素,雨季的强降雨及人类生产活动常常是地质灾害产生的诱发因素。

THE GEOLGICAL DISASTER FEATURE AND STUDY ON THE DISASTER-FORMING RULE IN SHIPING,YUNNAN

Shiping,Yunnan is in the S part of Yunnan,the altitude decreases generally S-wards to the Honghe river valley.The geological structure is complicated and geological environment is weak.According to the investigation on the spot,the geological disasters include slide,collapse and debris flow.These geological disaster spots are generally distributed along the fault.The high mountain and steep slope in Shiping are the important control factors of geological disasters.The strong raining in raining season and production activities of people are the induced factor of geological disaster as usual.
