摘要:
泥石流灾害作为当今世界上爆发频率较高的地质灾害之一，严重威胁到了国家及人民的生命财产安全。本文对国内外暴雨型泥石流监测预警技术研究现状进行了梳理，对陕北黄土高原泥石流监测预警现状进行了总结，对未来暴雨型泥石流监测技术的发展趋势进行了展望，提出了比较科学的临界降雨量阈值的确定方法。认为陕北黄土高原暴雨型泥石流监测预警不能只停留在对降雨量的监测和预报上，应结合流域水文模型和地理信息系统，综合地形地貌因素，这样才能大大提高监测和预报的精度。
As one of the geological disasters with high frequency in the world today, Debris flow disaster is a serious threat to national people’s lives and properties. This paper reviews the current domestic and foreign researches on the rainstorm debris flow monitoring and early warning technology, summarizing and generalizing the current situation of Debris flow monitoring and early warning in the Loess Plateau of Northern Shaanxi. This paper brings to focus further development on Mon-itoring technology of future rainstorm type debris flow, and puts forward a comparative scientific method about Critical rainfall threshold. Rainstorm debris flow monitoring and early warning in Loess Plateau in Northern Shaanxi can not only stay on the monitoring and forecast of rainfall, but also combine with the hydrological model, geographic information system, and comprehensive topographic factors, so as to greatly improve the accuracy of monitoring and forecasting result.
