【Abstract】 Based on the structural equation model’s confirmatory factor analysis,this essay improves the method of the determining of dimensions and influencing factors of urban vulnerability research. And it uses the A- F method to reduce the ambiguity of traditional measure. Then this essay measures the Yangtze River Economic Belt ’s vulnerability. The results show that the degree of Yangtze River Economic Belt’s vulnerability locates at the higher level; In space,it shows obvious ladder characteristics; There are quite internal difference in vulnerability.更多还原
