【摘要】：随着山洪灾害监测预警非工程措施建设和全国2013年-2015年度山洪灾害防治建设的推进,宁夏全区防洪减灾综合能力得到了显著改善和全面提升。但现阶段尚没有科学、系统、定量的分析研究突发暴雨、洪水、积涝、滑坡、泥石流等山洪灾害预警指标,突发性洪涝灾害的应急避灾、紧急处置和抢险救助仍旧十分困难。结合宁夏水系分布与防洪工程建设实际情况,在参考已有临界雨量推求方法的基础上,综合应用暴雨等值线和P-Ⅲ频率曲线表反推不同量级洪水对应的雨量值作为山洪灾害预警值。该方法简单易操作,计算成果对宁夏防洪减灾工作具有重要意义。
[Abstract]:With the construction of non-engineering measures for mountain flood monitoring and early warning and the construction of mountain flood disaster prevention and control in the whole country from 2013 to 2015, the comprehensive ability of flood control and disaster reduction in Ningxia has been significantly improved and comprehensively enhanced. But at present, there is no scientific, systematic and quantitative analysis and research on the early warning index of sudden torrential rain, flood, accumulation of waterlogging, landslide, debris flow and so on, the emergency prevention of sudden flood and waterlogging disaster, emergency treatment and emergency rescue are still very difficult. According to the actual situation of Ningxia drainage system distribution and flood control project construction, on the basis of referring to the existing methods of calculating critical rainfall, The rainstorm isoline and P- 鈪，
