Abstract:

Taking project guarantee,social economy guarantee,environmental guarantee and efficiency guarantee as criterion layer,12 indicators including water deficient ratio,effective irrigated area ratio and water consumption per unit GDP etc.as indicator layer,the evaluating indicators of waterresource guarantee for Nantong City is constructed.The Analytic Hierarchy Process (AHP) and expert grading method are used to determine the weight of each indicator,and weight average methodology is used to get the evaluation result.Results demonstrate that Nantong City owns a medium waterresource support capability now and will improve to some extent in the future on the basis of saving water,protecting environment and increasing wateruse efficiency.From the results of every criterion layer,the engineering project owns the best capability,while the environment owns the worst capability for the development of Nantong City.From the result of every district,the integrated support capability of Rugao City is the best,while the Rudong City and Hai’an City are the worst.At last,a discussion on how to improve the waterresource guarantee for every district is made
