Establishment of the Performance Evaluation Model of Integrated Water Resources Management and Empirical Study

Abstract

Based on the socioeconomic development goals of water resources management in a typical river basin of China, this paper puts forward a performance evaluation index model of integrated water resources management (IWRM), classifies the model into four evaluation dimensions by the hierarchical structure of AHP, such as environment sustainability, social fairness, economy benefit and organization energy efficiency, and further divides the four evaluation dimensions into 18 evaluation indices. Besides, this paper establishes a theoretical evaluation system of IWRM performance in different basins on the basis of binary comparison, entropy weighting and linear superposition, and effectively reveals the change trend of IWRM performance in different basins. The results show that the key to IWRM lies in sustainable development of water resources environment, the utilization ratio of water resources and the corresponding economic benefits, and that the rational utilization of water resources is conducive to rapid economic development. From 2003 to 2014, the IWRM performance index in the five basins increased gradually, and the growth rate of the performance indices increased first and then decreased. The change trend of IWRM performance in the five basins is basically the same with that of the performance index.
