我国是一个山地灾害多发的国家,尤其是近年来频发的山地灾害,给国家和人民造成了巨大的损失。通过对2010年8月7日甘肃省甘南州舟曲特大山洪泥石流灾害状况、自然和人为因素的分析,详细阐述目前我国在应对突发性山地灾害预警及管理中存在的问题:排查精度低、灾害预警技术低、信息不畅、灾害应对体系不完善。针对各问题提出提高排查精度、开展以流域为单元的地质灾害详细调查和危险区区划、建立和管理灾害信息共享平台、完善灾害应对体系等建议,可为今后泥石流灾害预警预报提供科学依据。
Our country is a country with frequent mountainous disasters, especially the mountainous disasters that have been frequent in recent years, causing huge losses to the country and its people. By analyzing the status, natural and man-made factors of the debris flow disaster in Zhouqu, Gannan Prefecture, Gansu Province on August 7, 2010, this paper elaborates the current problems in early warning and management of sudden mountainous disasters in our country: low precision of investigation, Disaster early warning technology is low, poor information, disaster response system is not perfect. To improve the accuracy of investigation, to carry out a detailed investigation of geological disasters and risk zone zoning as a unit, to establish and manage disaster information sharing platform and improve disaster response system for various issues, and so on, can provide a scientific basis for early warning and forecast of debris flow disasters.
