英文摘要	Lakes and reservoirs are important components of freshwater. The expansion and shrinkage of lakes/reservoirs may have impacts on meteorological characteristics and the underlying surface conditions in the surrounding areas, which would further affect energy and water vapor fluxes. In this study, the expansion and shrinkage of the Guanting Reservoir during 2013–2017 were analyzed using remote sensing data. Data collected from the Huailai Remote Sensing Experiment Station were used to analyze the impact of reservoir expansion/shrinkage on energy and water vapor fluxes in the surrounding area. Results showed the annual expansion of the Guanting Reservoir from 2013 to 2017 and a seasonal variation characterized by expansion in spring, shrinkage in summer and autumn, and expansion again in winter was exhibited. Meanwhile, the evapotranspiration (ET) in the surrounding area increased by about 96%, from 446.6 mm in 2013 to 874.7 mm in 2017. In growing season (May to September), the seasonal shrinkage of the reservoir affected ET through net radiation, normalized difference vegetation index (NDVI), and deep soil moisture, while in nongrowing season (January to April and October to December), the seasonal expansion increased ET through the distance between 40-m tower and the reservoir, net radiation, and surface soil moisture. In addition, with the reservoir expanding year by year, the difference in ET between the closer site and further site from the reservoir increased obviously, especially in the nongrowing season during the seasonal expansion of the reservoir. The findings of this study are beneficial for ecosystem restoration and sustainable development of lakes/reservoirs in arid and semiarid areas. ©2020. American Geophysical Union. All Rights Reserved.
