Abstract: According to the current situations of water resources, water environment, water resources management and information statistics in China, the paper readjusts the evaluation index system of water risk for river basin based on the evaluation index system of water risk presented by WWF and DEG, and makes it more suitable for the national condition of China. The indexes are graded by five-grade and five-score scale. Also, the weights and calculation methods of some indexes are adjusted. The weighted comprehensive index summation process is adopted to calculate the integrated evaluation score of basins. The comprehensive evaluation is conducted in the Yangtze River Basin and its seven secondary subareas. The results show that the risk scores of the Yangtze River Basin and its subareas in 2010 are between 1.1 and 1.8, and the risk grade is class Ⅱ, which means it is a low risk area. There are some differences among the scores of the secondary subareas. The scores of the Taihu Lake water system and the Hanjiang River are relatively high. The score of the Jialing River is the lowest. The contribution rates of the three categories of indexes to the water risk are different. The physical risk has a relatively higher influence on the water risk, its contribution rate being 45%-60%; the second one is the regulatory risk, and the contribution rate is 21%-32%; the reputational risk has a lower influence and the contribution rate is lower than 25%. Finally, the future research directions in the field of water risk evaluation are proposed based on the existing problems in the course of China water risk evaluation.
