摘要
本文根据大量实测及历史资料,论证了黄河上游存在与中游同步的1922～1932年连续11年枯水段,该枯水段的出现机率为200年一遇。建议以1951～1975年水文系列作为黄河水资源规划和水利计算的代表系列。
1922-1932 A. D. was a continuous low water period 11 years long in the Yellow River Basin. Based on the measured data of the waterlevel scale at Qingtongxia and Wanjintan from the beginning of the eighteenth century (the Qing Dynasty) and the water regime reports to the Emperor by local officials, this paper estimates high and low water regime for the past 200 years. Combining these estimates with stochastic hydrology calculation, it is concluded that the recurrence period of the continuous low water period (1922-1932) is 200 years at least. The conclusion is rather important to recognizing year-to-year variation of the Yelleow River water resources and to development and use of the Yellow River water resources.
