%X 收集黄家港和皇庄水文站1954~2020年日均流量数据，分别以丹江口水库建成蓄水和南水北调中线工程通水为时间节点，将长序列资料分为三个研究时段，选用水文改变指标(IHA)和变化范围法(RVA)，分析计算建库以及调水对汉江中下游水文情势的影响。结果表明：黄家港站整体水文改变度在丹江口水库建库后为53%，在调水后为64%，为中度改变，其中流量增减变化最为显著。水文情势的中度改变直接影响汉江中下游的水环境和水生态，有必要进行生态修复和生态调度措施。<br />
The daily average flow data of Huangjiagang and Huangzhuang hydrological stations from 1954 to 2020 were collected, and the long-time data series were divided into three periods based on the Danjiangkou Reservoir and Mid-route of south-to-north water transfer project. Indicators of hydrologic alteration (IHA) and Range of variability approach (RVA) method were selected to analyze the impact of reservoir construction and water diversion on the hydrological regime in the middle and lower reaches of the Hanjiang River. The results show that the overall hydrologic alterations of Huangjiagang station is 53% after the built of Danjiangkou Reservoir, and increases to 64% after the water diversion. The hydrological regimes of three periods of two hydrological stations are all moderate alteration, also the rate and frequency of hydrograph has changed greatly. Moderate alterations in hydrological regimes directly affect the water environment and ecology in the middle and lower reaches of the Hanjiang River, and it is necessary to carry out ecological regulation and restoration.
