为了研究成都市水资源的可持续发展现状，在PSR模型的基础上，充分结合成都市的实际情况建立了城市水安全评价指标体系，采用层次分析法计算各指标的权重，最终得出成都市水安全评价综合指数，并使用相关分析方法，对未来水安全情况进行预测。结果表明：2005年—2013年成都市水安全状况均处于安全状态。为了进一步保证社会、经济、资源、环境的协调发展，提出了如下建议：采取措施来提高市民的节水意识；加大技术投入，建立节水型城市；实现水资源的合理利用，提高水资源的利用率；增加环境投资，提高工业和生活污水处理率；完善城市水资源管理系统和预警机制，提升应对突发性水环境事件及水资源问题的能力。

In order to investigate the present situation of sustainable development of water resources in Chengdu, this paper adopted the PSR model to establish the index system of water security assessment of Chengdu, determined the weights for each index using the AHP method, obtained the comprehensive index of water security assessment of Chengdu, and predicted the future water security using the correlation analysis method. The results showed that the water security level of Chengdu is grade IV from 2005 to 2013, indicating a security status. Meanwhile, in order to ensure the coordinated development among society, economy, and environment, several suggestions were proposed in this paper, including the improvement of consciousness of saving water and establishment of a water-saving city through increased technical investment, the increasing of utilization rate of water resources, the increasing of environmental investment to enhance the rate of municipal and industrial waste water treatment, and the improvement of water resource management system and early warning mechanism to strengthen the ability of coping with the accidental water environmental and resource problems.
