This paper established the earthquake disaster risk assessment index system for Gansu Province firstly, determined weights of index factor, and then calculated the earthquake disaster risk, exposure, vulnerability and disaster prevention and mitigation capacity based on GIS software platform, finally mapped the earthquake disaster risk of Gansu Province. The results show that: (1) In macroscopic view, the occurring frequency of earthquake disasters in Gansu was relatively high. The high risk region of earthquake disaster mainly concentrated in three areas of Liangzhou District of Wuwei - Gulang, Tianshui - Dingxi, Longnan - Gnana and presented high spatial agglomeration. (2) Highest risk, higher risk, medium risk, lower risk and lowest risk areas accounted for 4.65% (20.3 thousands), 16.67% (72.8 thousands kilometers), 21.13% (92.3 thousands kilometers) and 26.42% (115.4 thousands kilometers) of total area, respectively.
