Abstract:The goal of water governance is specified from five dimensions, including resources, economy, sociality, ecology and environment. The evaluation index system of the water governance in China is systematically designed. The current situation of water governance is comprehensively evaluated and the variation trend of China's water governance in 2020-2050 is forecasted using the hierarchical equal weight method and the target consistency method. The results show that the index of water governance has been increased quickly from below 0. 235 to near 0. 70 since the reform and opening-up. The acceleration period of water governance is from 2010 to 2015, in which the water governance index has increased about 50%. It is expected that the water governance index will exceed 0. 85 by 2020, and the harmonization between economic development and water resources utilization will be realized. The index of water governance will reach 0. 95 by 2030, and the harmonization between economic development and water pollution will be realized. The capacity of water safety support can be significantly improved and the water governance targets can be realized basically. The index of water governance will reach the optimum value of 1 by 2050, and the water resources utilization, water pollution discharge, water disaster loss and water ecology degradation area will be zero growth, fully achieving the harmony between human and water.
