To understand the vulnerability of Daqing's urbanization, this paper, based on its connotation of vulnerability and Daqing's situation, established an evaluation index system from destabilization intensity, sensitivity, adaptability and measures, uses normal cloud evaluation model to measure the vulnerability of Daqing's urbanization during 1995-2015 with results showing an improving urbanization, the overall vulnerability declines to medium from high. Four standard levels also fall in vulnerability class. Destabilization intensity vulnerability declines steadily and sensitivity vulnerability also declines but fluctuates since 2008. Adaptability increases slowly with its vulnerability descends to medium from relatively high, a principal factor in limiting Daqing's urbanization development. Economic transformation brings boosts adaptability, but its basis needs to be stabilized, fluctuating since 2009. In general, Daqing's urbanization is of relatively high vulnerability, which demands a higher adaptability and measures. 
