摘　　要：以东江流域控制站点博罗站为代表,通过构建一维水流水温模型,计算分析了东江三大水库不同出库流量对下游惠州河段水温的影响,探讨了该地区基于水温的鱼类生态调度目标,提出了东江三大水库3月份的水库联合生态调度方案。研究结果表明,在东江三大水库出库流量比例不变的情况下,博罗站3月份水温随着流量的增大而增大,但变化并不明显;在博罗站流量不变的情况下,东江三大水库出库流量的变化对博罗站水温有较大的影响,其中以白盆珠水库的影响最为显著。结合前人的研究成果认为,在博罗站流量320m3/s的情况下,保持白盆珠水库3月份最小出库流量为30m3/s,有利于东江下游惠州河段的生态条件改善。With the Boluo Station of the Dongjiang River Basin as a case study, the influence of water temperature in the Huizhou Reach under different flow releasing conditions of the three large reservoirs was analyzed, the ecological operation goals based on water tempera- ture were discussed, and the joint ecological operation scheme of the three large reservoirs in March was proposed, by using 1D flow and water temperature model. The results show that under the same proportion of outflow among three large reservoirs, the water temperature increases at the Boluo Station in March when the flow increases, but changes little; Under the same flow at Boluo station, the different out- flow of three large reservoirs, especially Baipenzhu, have great effects on the water temperature in the Huizhou Reach. Combined with for- mer research results, in condition of keeping the flow the of Boluo Station at 320m3/s, we recommend the least outflow of the Baipenzhu Reservoir at 30m3/s in March, which is good for the ecology in the Huizhou Reach of the Dongiiang River.
