摘要
利用清代奏报中保留的汛期涨水尺寸记录,近现代以来黄河中游水文站存在的水位信息器测数据,基于1766～1911年黄河中游万锦滩(位于今河南省三门峡市)水位志桩所载涨水时间,在"侯"尺度下建立了研究时段内三门峡断面的汛期开始时间。结果表明:1766～1911年,1840年代前中游汛期开始时间在平均水平;1840～1860年代汛期建立时间偏晚;1860～1890年代再次开始提前。在研究时段内黄河中游汛期开始时间平均为7月上旬,与同时期长江中下游梅雨结束时间有很好的对应关系,但年际差异较大,夏季风雨带推移成为导致中游汛期开始时间产生波动的主要驱动因素。
In this study, we used the water level records of flood season for the middle reaches of the Yellow Riv- er Wanjintan in the Sanmenxia city, Henan province by Qing government and modern hydrological stations during 1766 - 1911, and reconstucted the curve of floodseason beginning time under pendate scale. The results showed that before the 1840s flood season starting time was on average; in 1840s ~ 1860s the flood season time was later than avwerage; in 1860 N 1890s,flood season time began again ahead of average. In the study period the flood season start time was at an average of in early July, with the same period with in the end time of plum rain over middle and lower Yangtze River. There is a good corresponding relationship between of them. Summer rainband in the east - middle China is the cause of flood season start time due to the fluctuation of the main driving fac- tors.
