DYNAMIC PERFORMANCE EVALUATION OF WATER RESOURCES MANAGEMENT IN SEVEN RIVER BASIN OF CHINA

Based on literature research and field investigation,the connotation of performance evaluation of water resources management was given,the indicator system of performance evaluation and a dynamic evaluation model of water resources management in seven River Basin of china was designed,with reference to the socioeconomic development objectives of water resources management.The model was used to analyze the changing trend of the performance index of water resources management in 1999-2010,and revealed the causes of its changing trend. Then,the superiority and inferiority of performance level among different drainage areas was comparatively analyzed.Results showed the performance index of water resources management of seven drainage areas in China was improved with different levels during 1999-2010,the order of the growth rate of the performance index is Haihe River,Yellow River,Songliao River,Taihu Lake,Pearl River,Yangtze River,Huaihe River,and the order of relative management performance level is Haihe River,Pearl river,Huanghe river,Songliao river,Taihu Lake,Yangtze river,Huaihe river.During 1999-2003,the highest management performance level is Songliao River Basin.During 2003-2007and 2007-2010,the highest management performance level is Pearl River Basin, During 1999-2010,the lowest management performance level is Huaihe River Basin.The study also revealed that the performance index of water resources management was greatly influenced by per capita water consumption, comprehensive water consumption rate,agricultural water proportion,water use per industrial GDP,waste water discharge per GDP,and utilization ratio of water resources.
