Abstract：Taking Shenfu New City as the research object,a comprehensive evaluation model of urbanisation was established based on a four-dimensional framework(population,economy,space and society).The PSR(Pressure-State-Response)model was introduced to construct the water ecology assessment index system,and the dual system responsiveness and coordination model was set up.Analysis results indicated that from 2000 to 2014,the regional urbanisation index showed a significant upward trend,while the water ecological quality underwent a"U-shaped"evolution,initially decreasing and then increasing.The co-ordination model revealed that the systemic relationship changed from extreme imbalance to co-ordinated development,reflecting the effectiveness of environmental policy regulation.The impact of the urbanization process on water ecology exhibited a threshold effect:once the critical point of environmental carrying capacity is breached,ecological degradation trends can be reversed through investments in environmental governance.
