摘要： Based on the concept model of PSR (Pressure-State-Response), and referred to the current assessment methods of the ecological security evaluation, relating AHP to construct evaluation system, this study combined the impact factors of natural, social and economic on Valley Region ecological security, the mutual influence and restraint law of the internal system between various factors, AHP was used to establish the ecological security assessment indicators system of Beijing Valley Region. Compared with 2005 increased 0.08, The score of ecological security about Puwa Valley Region was 0.63 which attained general status. At last, this study promoted corresponding advices.
