中文摘要	用熵值法和贡献度模型，对河西绿洲城市的干旱脆弱性及主要贡献因子进行分析。结果表明：张掖市、酒泉市和金昌市城市干旱脆弱性均处于中等水平，嘉峪关市干旱脆弱性水平较低，武威市干旱脆弱性水平很高；河西绿洲城市干旱脆弱性的空间分异与城市化水平基本一致，敏感性与城市化水平关系密切，应对能力受经济水平和自然因素的影响，但自然条件发挥防御干旱的应对作用更大；各市干旱脆弱性指标层的主要贡献因子不尽相同，但总体呈趋同态势，主要集中表现在社会干旱敏感性及应对干旱的技术、自然条件等因子上。最后，有针对性地提出了具体的对策与措施。
英文摘要	Using the entropy method and the model of contribution, the drought vulnerability and its major contribution factors in Hexi oasis were analyzed. The results showed that: the drought vulnerability in Zhangye City, Jiuquan City and Jinchang City were in the medium level, which in Jiayuguan City was in the low level and in Wuwei City was in very high level. The spatial differentiation of drought vulnerability in Hexi oasis was consistent with urbanization level, the sensitivity to drought was closely related with urbanization level, and the ability to cope with drought was affected by economic development and natural factors, but the former’s effect was more than the latter. The main contribution factors were not the same in the index hierarchy of drought vulnerability among different cities, but shared generally a convergence trend, mainly in reflected in social drought sensitivity and response to drought, natural conditions, etc. Finally, corresponding countermeasures were put forward to drought vulnerability.
