摘要
滩坑水电站下游为国家一级保护水生动物鼋的保护区.采用剖面二维水温模型对滩坑水库下泄水温进行了模拟,然后采用一维非恒定水流水温数学模型对建库后滩坑电站下游鼋保护区内水温变化情况进行了预测,对比分析了平水年条件下,不同电站开机组数和不同电站取水口高程条件下水库下泄水温对坝下游河道鼋自然保护区鼋的影响.分析表明可抬高电站取水口高程使下泄水温与天然水温较为接近,以尽量减小由于发电而给下游河道生态造成的不利影响.
The downstream reach of Tankeng Hydropower Station is a key protection area of Pelochely bibroni. Vertical two-dimensional water temperature mathematical model was used to simulate the discharged water temperature of Tankeng Hydropower Station; and one-dimensional unsteady flow and water temperature mathematical model was used to forecast the changing water temperature along the downstream reach, where the Pelochely bibroni protection area was covered. Computed results indicate that it is needed to adjust the intake elevation to make the temperature of discharged water close to the nature water temperature.
