Abstract:  As a special type city, resourcebased cities have four parts of its vulnerability, including resource vulnerability, ecoenvironmental vulnerability, economic vulnerability and social vulnerability. Discussing the vulnerability measures and dynamic evolution characteristics of the resourcebased cities has great significance to its transformation development. This paper took Panzhihuathe typical resourcebased cities in the southwest area, as the research object, focused on establish the vulnerability measure index system, utilized AHP(Analytic Hierarchy Process) to determine the index weight and adopted multifactor comprehensive evaluation method to study its vulnerability and dynamics. The results indicated that: (1) the trend of comprehensive vulnerability of Panzhihua in 2006-2015 was in decline. The index fell from 0.74 in 2006 to 0.37 in 2015, through the evolution of high vulnerability, middle vulnerability to low vulnerability. (2) In recent 10 years, the annual average of resource vulnerability (0.57) was the maximum in Panzhihua, followed by economic vulnerability (0.50), while the social vulnerability (0.46) and the ecoenvironmental vulnerability (0.43) were relatively small. In the meantime,the resources vulnerability, ecoenvironmental vulnerability and the social vulnerability were declining, their annual variation was 0.10, 0.10 and 0.08. However, the economic vulnerability rose by oscillation, with the maximum annual variation (0.13). (3) In recent 10 years, the contribution to economic vulnerability of urban comprehensive vulnerability in Panzhihua rose significantly (up from 15.53% in 2006 to 70.03% in 2015). At the same time, the contribution of the social vulnerability was also prominent (20.16% in 2015). In the future, Panzhihua should adhere to the economic transition of the core in the transformation and city’s vulnerability regulation, promote the resources comprehensive exploitation and utilization; further strengthen geological prospecting mineral resources; promote regional development as a whole and decrease the social vulnerability; improve the comprehensive utilization of the industrial solid wastes in order to enhance ecological environment protection.
