Based on the objective conditions which has formed Hengyang ecological environment, this paper studied the impact of the four factors of the ecological environment vulnerability about the seven counties or county-level cities of Hengyang city, and determined eight evaluation indicators, use the analytic hierarchy process, indicators the relative weights of corresponding evaluation, and through the evaluation model, obtaining all quantitative ecological environment vulnerability of the evaluation units. Evaluation results divided the ecological environment into five groups: extreme frail area (Hengyang County), serious frail area (Heangnan County and Qidong County), medium frail area (Hengdong County), mild frail area (Changning City) and latent frail area (Hengshan County and Leiyang City), and made the Hengyang ecological environment frail comprehensive evolution map. Finally, the Hengyang ecological environment management measure was proposed in view of the measured results.
