    Abstract
  • Natural disasters as geological disasters, floods,and earthquakes etc frequently occurred worldwide nowadays. The aggravation of the clustered disasters makes it an increasing concern how to reduce the risk of these disasters.This paper carried out a comprehensive assessment on the risk of multi-hazard natural disastersin Xianyang city of Shaanxi province.The results show that the risk zone presents obvious spatial differences.Overall, the risk is much higher along the WeiheValley and the northwestern mid-low hilly areas, spreading mainly in the southeast of Qindu District,the northwestof Wugong county,the urban area of Qianxian county,the eastern urban area of Sanyuan county,the urban area of Chunhua county, Binxian city and Xunyi county.In other regions,the risk of natural disasters is comparatively low.The results provide some references and guidance for the emergency managing and land space planning of Xianyang city.
