| Abstract: | Taking Yan'an city as a case,we selected 16 representative and comprehensive indexes of resource,environment and social economy which could reflect the research area's ecological character to build assessment system for ecological vulnerability.On the basis of determining the weight AHP,we used method of composite index evaluation to separately calculate the ecological vulnerability values from four aspects,including natural ecological background,ecological sensitivity,human disturbance and human adaptabili... |
