Abstract
Moisture recycling by terrestrial evaporation and transpiration has recently been confirmed as an important source of precipitation, but little is known of this contribution in inland river basins of China. This study determines the fractions contributed by terrestrial evaporation and transpiration to precipitation in the Shiyang river basin, located in Gansu province of northwestern China. The basin has an area of 4.16 × 104 km2 and mean annual precipitation of 300 mm/yr. Hundreds of samples of precipitation, surface water, plant stem water and soil water were collected and analyzed for their isotopic compositions. The Craig-Gordon model and a three-end-member mixing model were used to part..

Data on stable isotopes for different water samples are available from the corresponding author. Data on precipitation amount, air temperature, wind speed and relative humidity were recorded at corresponding automatic meteorological stations in three mountainous sampling stations by the corresponding author; the metrological data for the other three stations were from Minqin, Wuwei and Yongchang national meteorology observation stations, and were from China Meteorological Administration (http://www.nmic.gov.cn/).
