Abstract Based on the definition of ecological environment system vulnerability of oasis cities, the entropy method was used to assess the vulnerability of the ecological environment system of oasis cities in Xinjiang. Results showed that: (1) The ecological environment system become more vulnerable with the increase of the spatial scale of oasis cities. (2) Among the oasis cities with different development types, cities with industry and oil exploitation as dominant industries are more vulnerable than those with business and trade, tourism and primary processing of agricultural products as dominant industries. (3) The east Xinjiang is more vulnerable than the north Xinjiang, and the north Xinjiang is more vulnerable than south Xinjiang. (4) The main factors that affect the vulnerability of the ecological environment system of oasis cities are the system's sensitivity to environment pollution, the consumption of energy and water resources. Finally, the 21 oasis cities in Xinjiang are categorized into four types according to their ecological environment vulnerability characteristics.
