Abstract:: Water environment security is a key limiting factor in the economic development. Based on the construction of Pressure-State-Response (PSR) model, water environment security is examined and assessed in Yancheng City in the coastal development region in Jiangsu by utilizing the analytic hierarchy process (AHP) weighting method. Assessment results show that there is an increasing trend of the index of the water environment security in Yancheng City, results also reveal that water environment is getting better than before which is resulted in the positive policy on the water environment. With the increasing pressure of population and the GDP increase, industrial water demand, qualified waster water discharge and investment on the environment are the key point for lowering the risk of the water environment. The risk of the water environment can be reduced by optimizing the water resource distribution, accelerating the upgrading of the industry, advancing into a new road to the urbanization and industrialization, decreasing the demand of industrial water consummation, and increasing the investment on the environment and the restoration of the forestland and the green land in Yancheng City.
