摘要
本文从实测资料分析了乌江渡电站水库坝前水温的变化规律及其影响因素,该水库水位年变幅较大,库水交换频繁,加之水库异重流的影响,深层水温年变幅较大,不能形成稳定的低温区,有其变化特点。通过逐步回归分析表明,水温主要与气温的滞后因素有关,并提出了一些看法。
Based on the observed data, the variation of water temperature of the Wujiangdu Reservoir in front of the dam is analyzed, and the factors affecting the variation are investigated. The amplitude of annual variation of the reservoir level is comparatively large, the exchange of reservoir water is frequent, and there exists density current which leads to the large annual variation of deep water temperature, therefore a stable low temperature zone cannot be formed. Step-by-step regression analysis indicates that water temperature is related to the lag factors of air temperature. Some opinions are put forward in this paper.
