【摘要】：水庫(kù)水溫分層影響下游魚類等的繁殖和農(nóng)業(yè)灌溉作物的生長(zhǎng)。采用EFDC模型,建立三維水動(dòng)力模型,模擬湯村水庫(kù)水溫特性,分析水庫(kù)水溫時(shí)空分布特征。結(jié)果表明:湯村水庫(kù)從水面到水面下12 m水溫隨氣溫變化而變化,庫(kù)表水溫在1.0~28.5℃之間變動(dòng),8月水庫(kù)水溫最高;水體水溫隨水體深度增加而下降,且沿水深方向下降梯度逐漸變小,1月水庫(kù)表層水溫與中下層水溫基本一致;河道水溫在壩址下游約3 000 m處恢復(fù)至天然河道水溫,水庫(kù)下泄水體溫度對(duì)天然河道影響較小。
[Abstract]:Reservoir water temperature stratification affects the reproduction of downstream fish and the growth of agricultural irrigation crops. Using EFDC model, a three-dimensional hydrodynamic model is established to simulate the water temperature characteristics of Tangcun Reservoir and analyze the temporal and spatial distribution characteristics of reservoir water temperature. The results show that the water temperature of 12 m below the water surface of Tangcun Reservoir varies with the temperature, and the water temperature of the reservoir surface varies between 1.0 鈩，
