| 摘 要： | 根据水文变异指标法及变化范围法(IHA/RVA),对江西修水流域上游两个大型水库启用日期差异进行组合,定量计算、分析了水利工程影响下的修水流域上游枯水流量的时序变异特征,探讨了水利工程建设前后导致的水文变异程度,揭示了对河流生态系统至关重要的低流量范围内多个枯水情势高改变度的存在,为水库生态调度与河流生态保护提供了有益的参考。

| Abstract: | Based on Indicators of Hydrologic Alteration（IHA）and Range of Variability Approach（RVA）， the combination and quantified calculation are made on the difference between the impoundment dates of two upstream large reservoirs within Xiushui River Basin in Jiangxi Province， and then the characteristics of the time-series variation of the upstream low water flow of Xiushui River Basin under the influences of the water control projects concerned are analyzed; in which the hydrological variation extent before and after the constructions of the water control projects are discussed， while the existences of several high alteration degrees of withered water regimes within the ranges of the low flow-rates those are quite important for the eco-system of the river are proved up as well. This provides a beneficial reference for the eco-regulation of reservoir and eco-protection of river therein. |
