近年来,宁蒙河段凌汛灾害较为严重,槽蓄水增量是导致宁蒙河段凌汛灾害发生的关键因子之一。采用相关性分析原理,从气温、上游来水情况及前期形成的槽蓄水增量等多方面发掘影响宁蒙河段旬槽蓄水增量的因子,并分析了不同影响因子对旬槽蓄水增量的影响程度。结果表明,前期已形成的槽蓄水增量是凌汛期旬槽蓄水增量的主要影响因子,其次是气温,最后是上游来水情况。研究成果可为宁蒙河段防凌调度提供参考。
In recent years, the Ningxia-Moutain section has more severe flood disaster, and the increment of trough water storage is one of the key factors that cause the ice flood disaster in the Ning-Meng section. Based on the principle of correlation analysis, factors influencing the water storage increment in the ten-day trough of Ningmeng reach were explored from the aspects of air temperature, upstream water inflow and the increment of trough water storage formed in the early stage. The effects of different influencing factors The impact of incremental water. The results show that the increment of trough water storage formed at the early stage is the main factor affecting the trough water storage increment in flood season, followed by the air temperature and finally the water inflow in the upper reaches. The research results can provide a reference for anti-Ling regulation of Ningmeng reach.
