Theory of vulnerability is a tool to analyze interactions and mechanisms of human-land relationships and provides a new perspective on sustainability evaluation research. Here,we took the Han Dynasty Chang’an large relic area as an example and based on the concept of vulnerability evaluated the vulnerability of the human-land system using Fuzzy AHP and spatial analysis technology. The results show that the degree of vulnerability of the relic area is generally low:the low degree vulnerability area is concentrated and the high degree area is scattered along the edge of the relic area. The degree of society vulnerability is generally high:the high degree vulnerability area is concentrated,and society vulnerability in the northwest area is high and low in the southeast. In the large relic area,a weak degree vulnerability area in the whole area accounts for 27.2%,low degree vulnerability area accounts for 23.8%,moderate degree vulnerability area accounts for 27.9%,high degree vulnerability area accounts for 11.7%,and extreme degree vulnerability area accounts for 9.4%. The spatial distribution pattern of the vulnerability shows that the degree of human-land system in the north and west area is high,while in the south and east is low. The impact and stress of urbanization is the fundamental cause of vulnerability of the human- land system;residents’ rational choice is the internal agent of vulnerability of the human-land system;the externalities coming from protection policy to a certain extent affect the vulnerability of society.
