Abstract
Until now, most studies of the isotopic composition of precipitation in the Extensive Hexi Region have described individual sites. A systematic study considering the regional atmospheric circulation, the complex topography, and the re-evaporation process is lacking. This paper compares and summarizes previous studies in the Extensive Hexi Region, to provide a regional picture of the characteristics of isotopic composition of precipitation and moisture sources. δO and δD values exhibit significant seasonal variability, with higher values in summer and lower values in winter due to the seasonality of temperature and moisture sources. The temperature effect is more pronounced in the Extensive H..
