Abstract:: Global problems like population pressure, water pollution and so on have already make people recognize that the water security is becoming more and more important.Effectively assessing and monitoring the water security is significant to the human sustainable development.Firstly the article discussed the problems of water security in China, on which taken Ji’nan as the example, used the improved PSR model to construct water security assessment indicator system of water security in Ji’nan.Index weights of water security assessment indicators were determined by entropy method.Then get composite indices of water security assessment since 2000, on the basis of it carry through the correlation analysis and forecast.The results expressed that the composite index of Ji’nan had been increasing since 2000, with different models of pressure, state and response.Human economical activities have played an important role for that.Finally some suggestions were taken for water security problem.
