Abstract:
In order to identify the vulnerability of different areas under highway natural disasters, vulnerability assessment of every province was managed based on GIS platform. The influencing factors of vulnerability were analyzed from highway attribute, regional disaster management capability and distribution of regional road property. The assessment indicator system, including regional highway anti-disaster index, road network density and road property of per-unit, was also built. The Chinese Highway Natural Disasters Vulnerability Grading Map was generated through comprehensive assessment method and GIS platform. The results show that the natural disasters vulnerability degree of Chinese highway is 4. 30 to 7. 0, and the whole county is divided into very vulnerable, vulnerable, moderate vulnerable and minor vulnerable, the very vulnerable areas are Liaoning, Zhejiang, Shaanxi, Chongqing, Hubei, Yunnan, Guizhou, Hunan and Guangdong.
