黄河三门峡水文站1470～1918年年径流量的推求

Natural Annual Runoff Estimation from 1470 to 1918 for Sanmenxia Gauge Station of Yellow River

利用清代黄河报汛资料和《中国近五百年旱涝分布图》等有关资料，推求出黄河三门峡站１４７０～１９１８年的天然年径流系列，与陕县（三门峡）１９１９～１９８９年实测期的７１年资料，组成１４７０～１９８９年共５２０年的天然年径流系列。

In this paper, the data of flood alarm of Yellow River in Qing dynasty, the drought and flood distribution of China in recent 500 years, etc. are used to estimate the series of natural annual runoffs from 1470 to 1918 for Sanmenxia gauge station of Yellow Rivers, which consists of a series of 520 years natural annual runoffs with the 71 years observed data from 1919 to 1989 of Shanxian (Sanmenxia) gauge station.
