| 摘 要： | 基于水阳江中上游沙埠、港口湾、宣城三个水文站1974~2009年的日平均流量资料,采用逐月最小生态径流计算法、新逐月频率计算法和Tennant法分别计算和评价了三个水文站的最小生态径流和适宜生态径流,并对比分析了港口湾水库修建前后三个水文站径流过程的变化。结果表明,港口湾水库修建后,下游径流量呈秋冬增加、春夏减少、年内分配更均匀的趋势,部分月份月平均流量小于适宜生态径流值,研究成果可为港口湾水库生态调度措施的制定提供依据。 |
| 关 键 词： | 最小生态径流 适宜生态径流 径流变化 港口湾水库 水阳江 |

| Abstract: | Based on the daily flow at Shabu,Gangkouwan and Xuancheng hydrologic stations in upstream of the Shuiyang River during 1974-2009,the minimum and optimal ecological runoffs at the three stations are calculated and evaluated by using the monthly minimum ecological runoff calculation method,the new monthly frequency computation method and the Tennant method.Then the variations of runoff at the three stations are analyzed before and after construction of Gangkouwan Reservoir.The results show that the runoff has... |
