古浪-海原地区滑坡分布规律的模糊综合评判
|
摘要
本文在研究古浪-海原地区地震滑坡和重力滑坡形成条件和特点的基础上,首次采用多因素模糊数学综合评判方法对这一地区的滑坡空间分布特征进行了探讨和预测,提高了区域滑坡分布规律和危险性预测的深度和广度,为本区滑坡灾害的预测预防提供了重要的依据。
Based on the study of the generating condition and character of seismolandslide and gravity-landslide in Gulang-HaiYuan area, the comprehensive fuzzy assessment of multifactor is adopted at first time to explore and predict the spatial distribution character of landslides in this area, therefore, the prediction accuracy of distribution law and risk of landslides are improved , which provide important basis for the prediction and prevention of the landslide haz-ard in this area.
