摘　　要：为探究地理位置(纬度)差异对库区水温的影响,以规模和运行方式相似的温带功果桥水库和热带景洪水库为研究对象,基于原型观测数据和CE-QUAL-W2模型,对比分析功果桥和景洪水库库区水温分布特征。结果表明,CE-QUAL-W2模型适用于温带及热带水库水温模拟,且能明晰不同气候带水库水温变化差异;景洪库区表层水温升温与降温过程明显滞后于功果桥库区表层水温;功果桥水库和景洪水库均为弱分层型水库,功果桥水库春、夏季呈弱分层状态,秋、冬季的分层现象不明显;景洪水库夏、秋季呈弱分层状态,春、冬季的分层现象不明显。研究结果可为澜沧江类似规模电站的水温研究提供参考。In order to explore the influence of geographical location(latitude)differences on the water temperature of the reservoir area,the temperate Gongguoqiao Reservoir and the tropical Jinghong reservoir,which are similar in scale and operation mode,were taken the research objects.Based on the prototype observation data,the CE-QUAL-W2 model was established to compare and analyze the water temperature distribution characteristics of the Gongguoqiao and Jinghong reservoir.The results show that the CE-QUAL-W2 model can be applied to the simulation of temperate and tropical reservoirs,and the difference of water temperature changes in reservoirs in different climatic zones can be clarified.The temperature increase and decrease of the surface water temperature in the Jinghong reservoir area obviously lags behind the surface water temperature in the Gongguoqiao reservoir area.Both Gongguoqiao and Jinghong reservoir are weakly stratified reservoirs.Gongguoqiao Reservoir is weakly stratified in spring and summer,while the stratification in autumn and winter is not obvious.Jinghong Reservoir shows weak stratification in summer and autumn,but not in spring and winter.The results can provide reference for water temperature research of similar-scale power stations on the Lancang River.
