中国典型城市水资源利用效率评价研究

On the basis of the former literature survey, an evaluation indicator system of water use efficiency was developed. Using the Analytic Hierarchy Process (AHP) method, the main evaluation indicators were then selected and their weights were correspondingly calculated. A case study on the water use efficiency of ten typical cities in China illustrated the methodology. The results showed that the water use efficiencies of the cities in northern areas were higher than those in southern areas. The possible reasons were discussed. According to the calculated results, some measures were established to improve the water use efficiency of these cities in China.
