摘要
                
                    通过对1934年~1977年兰州、临夏、大武、玛曲、久治、达日等6站的旱涝等级和祁连山树木年轮资料、黑河莺落峡站径流量距平和通天河直门达站年径流量等诸因素与兰州站汛期天然径流量的关系及回归分析,建立了兰州站汛期(5~10月)天然径流量计算公式,重建了1485~2004年的天然径流量序列,并对其阶段性和周期性进行了分析。
                
                Through the regression analysis on the dry and flood degree in six stations as Lanzhou, Linxia, Dawu, Maqu, Jiuzhi and Dari, with the Qilianshan tree ring material, the runoff departure of Heihe Yingluoxia station andthe yearly runoff of Zhimenda station in Tongtianhe, and the relations of the natural runoff in flood season at Lanzhou station in 1934 to 1977, the natural runoff formula of the Lanzhou station at flood season (May~October) has been established, and the series of natural runoff from 1485 to 2004 has been rebuilt. Afterwards, the author analyzed the gradualness and periodicity on it.
