Study on Hydrogen and Oxygen Stable Isotopes in Precipitation in both Sides Along Taihang Mountain

Based on data of meteoric water hydrogen and oxygen isotopes and meteorology from 1986 to 1988 in Shijiazhuang and Taiyuan,we analyze the variation characteristics of stable isotopes in the two regions.It indicates that: 1) δD and δ18O in both regions show significant monsoon climate precipitation characteristics,which are high in the summer half year and low in the winter half year;2) The slope and intercept of meteoric water lines in Shijiazhuang and Taiyuan are smaller than that of China's meteoric water line equation;3) deuterium amount in both regions were relatively small,but both had seasonal characteristics,which was high in the winter half year and low in the summer half year;4) δ18O had relatively significant positive correlation with air temperature but weak positive correlation with precipitation in Shijiazhuang;δ18O had relatively significant negative correlation with precipitation but weak positive correlation with air temperature in Taiyuan.
