摘要
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, ice run disaster is more serious in the Ningxia-Inner Mongolia reach. Channel-storage increment is one of the key factors that lead to the ice run disaster in the Ningxia-Inner Mongolia reach. This paper adopts the principle of correlation analysis to explore the factors affecting the ten days channel-storage increment from temperature, upland water and the channel-storage increment formed previously and analyze the influence degree of different factors on the ten days channel-storage increment. The results show that the channel-storage increment formed previously is the main factor that effect the ten days channel-storage increment in the ice run season, the next factor is temperature, and then upland water. The impact factor research of the ten days channel-storage increment may provide a reference to the ice run prevention and deployment of the Ningxia-Inner Mongolia reach.
