Title: Characteristics of the δ~(18)O in Precipitation in the Upper and Middle Reaches of Heihe River
Abstract: The Heihe River,one of the long inland rivers in China,was confronted with water resources' scarceness owing to unreasonable development and utilization.To utilize effectively the limited water resources,isotope techniques was widely used to study hydrologic cycle.First of all,the characteristics of isotope in precipitation must be known.The relationships of δ18O in precipitation with precipitation,altitude,season and temperature are respectively discussed based on the study at some precipitation sampling sites in the middle basin and mountain areas of the Heihe River.It is found that δ18O depends on precipitation,altitude,season and temperature,and temperature is the most important factor.The dependence can be described by a multivariate linear regression equation.The fluctuation range of δ18O is very wide from season to season,more than 20‰.There is a better linear relation between δ18O in precipitation and temperature in mountain areas.The relationship between δ18O in precipitation and average temperature is better than that between δ18O in precipitation and the temperature before or after precipitation.
