摘要
水库水温预测方法在高海拔地区的适用性尚缺乏相关研究。对此,以旁多水库为例,运用经验公式法、垂向一维水温模型及立面二维CE-QUAL-W2水温模型对旁多水库水温进行预测。各预测结果与实测值对比表明,经验公式(张大发法和朱伯芳法)在旁多水库的水温预测中适用性较差,垂向一维水温模型和立面二维CE-QUAL-W2水温模型预测较为科学。在西藏高海拔地区水库水温预测中,建议将垂向一维水温模型和立面二维水温模型作为水温预测的主要方法,并提出了高海拔缺资料地区水库水温预测模型的运用建议。研究成果可为西藏高海拔地区的水温预测提供参考。
The applicability of reservoir water temperature prediction method in high altitude area is still lack of relevant research. Taking the Pangduo reservoir as an example, the empirical formula, vertical one-dimensional water temperature model and facade two-dimensional CE-QUAL-W2 water temperature model were used to predict water temperature of reservoir. Through the comparison of the predicted results and measured values, the temperature prediction formula of Zhang Dafa method and Zhu Bofang method in Pangduo reservoir has poor appheahihty, the vertical one-dimensional water temperature model and CE-QUAL-W2 temperature prediction model are more scientific. In the prediction of reservoir water temperature in high altitude region of Tibet, it is suggested that the vertical one-dimensional water tem- perature model and two-dimensional temperature model are taken as the main method for water temperature prediction, and this paper provides practical advice of using water temperature model in high altitude and lack of data area reservoirs. The research result can provide a reference for water temperature prediction in high altitude regions of Tibet.
