Abstract

[Objective] The ecological environment and climate in the West Ordos Desert of Inner Mongolia is fragile and sensitive. Study on the hydrogen(δD)and oxygen(δ18O)stable isotopic compositions and sources of precipitation in the West Ordos Desert is theoretically important to reveal the process of hydrological cycle in the West Ordos Desert and develop strategies for reducing or preventing land desertification and the use of regional water resource. [Methods] By using stable isotope technique, the compositions and relationships of δD and δ18O in precipitation and the effect of climatic factors on them in West Ordos Desert in summer were analyzed. Furthermore, the water vapor sources were determined based on HYSPLIT model. [Results] The relationship of δD and δ18O in precipitation in summer was δD = 7.287δ18O + 1.170. An apparent inverse correlation between stable isotopes and precipitation existed in the West Ordos Desert in summer (PP>0.05). The d-excess was positive and less than the global average d-excess (10‰), indicating that the precipitation in the West Ordos Desert was affected by ocean monsoon. The results of air mass back trajectories of summer precipitation using the HYSPLIT model indicated a dominant effect of local evaporation and continental northwesterly monsoon air masses in June and August, an effect of southeasterly monsoon on heavy rainfall (>30 mm), and the co-influence of oceanic monsoons southeasterly and southwesterly air masses in July. [Conclusion] The precipitation in the West Ordos Desert experiences evaporation effect. Analysis of precipitation and temperature effects indicates that the "amount effect" exists significantly, whereas the "temperature effect" is not obvious during summer. The water vapor from continental northwesterly, oceanic monsoons southeasterly and southwesterly, and local evaporation collectively have influence on precipitation in summer in the West Ordos Desert.
