摘要
本文利用石嘴山市近40年(1978—2017年)逐日降水观测数据、近2年(2017—2018年)区域自动气象站汛期(6~9月)逐日降水量数据资料,分析了石嘴山市暴雨天气时空分布和矿山暴雨灾害风险特征。结果表明:石嘴山市暴雨集中出现在每年的6~8月,强降水落区主要在贺兰山沿山平罗段崇岗镇附近。贺兰山沿山暴雨洪涝灾害孕灾环境敏感性高值区与石嘴山市极端降水落区非常吻合;暴雨危险度值空间差异较大,大武口暴雨危险度值最高。
Based on the daily precipitation observation data of Shizuishan in recent 40 years (1978-2017) and the daily precipitation data of regional automatic weather stations in flood season (June to September) in recent 2 years (2017-2018), the temporal and spatial distribution of rainstorm weather and the risk characteristics of mine rainstorm disasters in Shizuishan were analyzed. The results showed that the rainstorm in Shizuishan occured in July to August every year, and the main area was near Chonggang Town in Pingluo section of Helan Mountain. The high value area of environmental susceptibility of rainstorm and flood disaster along Helan Mountain coincided well with the extreme precipitation area in our city;the spatial difference of Rainstorm Risk value was large, and the Dawukou rainstorm risk value was the highest.
