摘　　要：为研究安康水库对下游生态水文情势的影响,以安康水库1991-2011年入库流量数据和水库下泄径流数据为研究对象,采用变化范围法(RVA)分析了水库修建前后对天然水文情势的变化情况,定量评价了水文情势改变程度。结果表明:人类活动对河流水文情势影响较大,安康水库运行阶段的整体改变度为39.21%,属于中度改变。生态水文特征的中度改变将对汉江中的水生生物和整个河流生态系统造成深远的影响。For studying influence of operation of reservoir on flow regime in low reaches, based on the reservoir lntlow and outtlow from 1991 to 2011, range of variability approach （RVA） is applied to analyze the hydrologic regimes of Ankang Hydrological Station before and after the impoundment of Reservoirs. The result shows that： Human activities have a long impact on the hydrologic re- gime, the overall degree of hydrologic alteration was 35.29%, it was belong to middle change. The middle change of eco-hydrological characteristics that would influence the aquatic organism in Hanjiang River,and greatly endanger the Entire river ecosystem.
