We produced and analyzed oasis structure information, and evaluated oasis functional stability using the multiple indicators based on Remote Sensing (RS) and Geographical Information System (GIS) in the arid region of China in 2015. The results showed that the oases area was 193,734 km 2 , accounting for 8.17% of the arid region of China. The spatial difference in the functional stability of oases was obvious. The Beijiang zone had the highest functional stability and was relatively stable state, and the Hexi Corridor‐Alashan Plateau zone had the lowest functional stability and was relatively unstable. The functional stability is dominated by production and ecological functions, which have regional differences. Increasing oasis agricultural output, strengthening highway infrastructure construction and paying attention to education will become important ways to improve oasis functional stability. Water resources determine the ecological function, thus affecting the oasis functional stability. The results provide references for the formulation of related policies according to local conditions.
