华北平原东部全新世古年地表径流量的估算

THE ESTIMATION OF ANCIENT ANNUAL SURFACE RUNOFF OF HOLOCENE IN EASTERN PART OF THE NORTH CHINA PLAIN

利用以现代数据建立的年平均降水量、年平均温度与年平均地表径流深间的关系式和全新世古年降水量、古年温度的推测值估算了华北平原东部的全新世古年地表径流深，并将估算结果与已有的古水文数据作了对比。

By using the relations between mean annual precipitation,mean annual temperature and mean annual runoff established with the climatological and hydrological data of the contemporary time, the values of ancient annual runoff of Holocene in eastern part of the North China Plain are calculated.These approximate values of the palaeorunoff obtained from the calculation are compared with the palaeohydrological information available in the same region. The result indicates that the conclusions are quite similar to those acquired from other methods.
