【摘要】：隨著山洪災(zāi)害監(jiān)測預(yù)警非工程措施建設(shè)和全國2013年-2015年度山洪災(zāi)害防治建設(shè)的推進,寧夏全區(qū)防洪減災(zāi)綜合能力得到了顯著改善和全面提升。但現(xiàn)階段尚沒有科學(xué)、系統(tǒng)、定量的分析研究突發(fā)暴雨、洪水、積澇、滑坡、泥石流等山洪災(zāi)害預(yù)警指標,突發(fā)性洪澇災(zāi)害的應(yīng)急避災(zāi)、緊急處置和搶險救助仍舊十分困難。結(jié)合寧夏水系分布與防洪工程建設(shè)實際情況,在參考已有臨界雨量推求方法的基礎(chǔ)上,綜合應(yīng)用暴雨等值線和P-Ⅲ頻率曲線表反推不同量級洪水對應(yīng)的雨量值作為山洪災(zāi)害預(yù)警值。該方法簡單易操作,計算成果對寧夏防洪減災(zāi)工作具有重要意義。
[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，
