Scientific assessment of the hydrological regime is an important part of the assessment of the health of the river ecological environment. The IHA indicators were used to quantitatively evaluate the change of hydrological indicators of Gaobazhou Station during the construction period and operation period of water conservancy projects in the Qingjiang River Basin. On the basis of analyzing the change law of five different IHA indicators, the overall hydrological situation change of Qingjiang River was analyzed by selecting three different RVA methods, which include the Nemero index method, the RVA method based on the European distance method and the RVA method considering the comprehensive weight. It shows that the results of the analysis of the hydrological situation in the Qingjiang River Basin by the three methods during the construction period and the comprehensive utilization period are moderate and highly changed, respectively, and the hydrological situation change in the Qingjiang River Basin has an increasing trend. The evaluation results of the RVA method considering comprehensive weights are similar to the previous two methods and are reasonable, which can better reflect the changes in the river hydrological situation after the construction of the water conservancy project in the Qingjiang River Basin.
