陇南、陕南片处于秦岭山区,滑坡、泥石流地质灾害分布广泛,危害严重,是我国4大滑坡、泥石流集中高发区之一,给该区国民经济的发展和人民生命财产的安全带来了严重威胁。在这类地区开展滑坡、泥石流监测预警,是我国20世纪90年代建设好生态环境,搞好防灾减灾工作中开展的一项新课题。该文阐明了滑坡、泥石流监测预警的含义与内容,分析了滑坡、泥石流的诱因,探索了在土石山区“土”法开展滑坡、泥石流监测预警的技术措施、方法和效益计算。
Longnan and Southern Shaanxi films are located in the Qinling Mountains. Landslides and debris flows are widely distributed and dangerous. They are one of the four major landslides and debris flow-prone areas in China, posing a serious threat to the development of the national economy and the safety of people’s lives and property in the area . Carrying out landslide and debris flow monitoring and early warning in such areas is a new topic for our country in building a good ecological environment and doing well in disaster prevention and mitigation in the 1990s. This paper clarifies the meaning and content of landslide and debris flow monitoring and early warning, analyzes the causes of landslide and debris flow, and explores the technical measures, methods and benefit calculation of landslide and debris flow monitoring and warning in the “soil” method in the mountainous areas.
