Abstract
Based on analysis of the runoff records of Shijiao hydrologic station,the hydrological regime change of Beijiang river basin was evaluated by RVA. It is concluded that various indicators are within the range of low altera⁃tion degree ~ middle alteration degree,with individual indicators up to high alteration degree; the operation regulat⁃ing of runoff reservoirs on main river and tributaries may affect significantly the hydrological regime of Beijiang riv⁃er basin during dry period,while renders minor influence during flood period; Feilaixia Reservoir has no much in⁃fluence on the downstream hydrological regime of Beijiang river,but the alteration degrees of some IHA are rela⁃tively high,so its regulation scheme requires further optimization to minimize the alteration degree,alleviate dam⁃age to natural ecological environment and create harmonious relationship between human and river.关键词
