Based on three national stations, Linze Station, Shapotou Station and Minqin Station, as well as the long-term positioning test platforms of Xinjiang Academy of Reclamation Sciences, Tarim University and Shihezi University, this project mainly studies the dynamic changes of typical oases in Northwest China in the past 60 years and their driving mechanisms; reveals the coupling of ecological and hydrological processes in typical oases, the water-heat balance differentiation law and the mechanism of maintaining the stability of the oases; and researches, develops, and optimizes and integrates key technologies for the maintenance of the oases' stability. Develop and optimize the integration of key technologies to maintain the stability of oasis: the integration of natural vegetation and artificial vegetation in the desert-oasis transition zone, the structure of water-saving oasis protection system and its spatial configuration technology, the technology of efficient soil and water utilization, the technology of joint utilization of surface water and groundwater, the technology of ground power enhancement, the technology of comprehensive management of sandy and salinized land, and the ecological industrial technology model of plantation and aquaculture integration; and research the uncertainty of water resource changes in oasis caused by climate change and human activities. It will study the uncertainty of oasis water resources changes caused by climate change and human activities, establish an evaluation index system for oasis functional stability and ecological security, build a decision support system for oasis adaptive management, and put forward a technical system and countermeasure suggestions for oasis adaptive management at different levels of human-water conflicts.
