宁夏西吉县境地震滑坡的地貌特征及其减灾开发对策探讨

Landform Characteristics of Seismic Landslides in Xiji County,Ningxia Province,and Discussion on the Countermeasures of Landslide Exploration and Disaster Mitigation

宁夏西吉县滥泥河流域在1920年海原8.5级大震时形成大量黄土滑坡及堰塞湖。本文阐述了西吉县境地震滑坡地貌的基本特征和当地人民对滑坡地貌的开发利用现状,分析了地震滑坡地貌所产生的环境灾害隐患,并针对该地区因地制宜开发利用滑坡地貌的减灾对策进行了探讨。

Many large-scale landslides and slide dammed lakes were formed during Haiyuan M8.5 earthquake in 1920 in Lannihe valley of Xiji county, Ningxia province. In this paper, the basic characteristics and the using situation of the slide landforms are expatiated, and the potential environment disaster caused by the landslides is analyzed also. Meanwhile how to explorate and use this landslides landform based on lacal condition, and how to mitigate the disaster are discussed.
