Abstract:: Hydrological regime is related to river ecological health and has an important influence on the integrity and stability of river ecosystem. Linear regression method, Mann-Kendall method, cumulative anomaly method and double cumulative curve method were used to analyze the runoff change characteristics of Xianyang, Huaxian and Zhuangtou hydrological stations in the Weihe River Basin from 1965 to 2018. IHA-RVA method was used to comprehensively evaluate the change degree of runoff hydrological indicators and reveal the impact of human activities on hydrological regime. The results show that the annual runoff of the main and sub-basins of the Weihe River showed a significant decreasing trend from 1965 to 2018(p< 0.05). The annual runoff reduction rates of Xianyang and Huaxian stations were 5.5×10⁷ m³/a and 6.8×10⁷ m³/a, respectively, and the annual runoff reduction rate of Beiluo River head station was 8.0×10⁶ m³/a. The abrupt change year of the annual runoff at Xianyang and Huaxian stations was the year of 1993, and the abrupt change year of the annual runoff at Fangtou station was the year of 1994. Compared with the changes of hydrological indexes before and after the mutation, the overall changes of Xianyang, Huaxian and Fangtou stations were 48%, 46% and 50%, respectively, which were moderate changes. Water conservancy projects and soil and water conservation measures were the main causes of the hydrological regime change. The results can provide the theoretical basis for the sustainable utilization of water resources and rational planning of soil and water conservation measures in this basin.
