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.
