Résumé partiel
The surface energy balance system includes net radiant flux,sensible heat flux,latent heat flux and soil heat flux.The heat exchange and evapotranspiration process between the surface energy and the atmosphere and its water cycle are closely related.The influence of underlying surface factors on surface energy is particularly important.Shallow groundwater has a greater impact on surface energy balance components through factors such as soil water content,surface temperature and long-wave radiation.The water source of Hatoucaidang is located in the hinterland of the arid and semi-arid Maosuwu Desert,with shallow groundwater level and abundant water.A newly-built water source for water supply in Kangbashi New District of Ordos City.This article conducts research on the impact of groundwater on the surface energy balance,which is helpful to explore the role of groundwater on the regional water cycle from the perspective of energy balance,and provides a scientific basis for the sustainable use of regional water resources and ecological environment protection.This time,the water source of Hatoucaidang was selected as the research area,and remote sensing images of different months of 2018 were selected in the study area,combined with the dynamic monitoring data of the water level of the in-situ test site and the water source of Hatoucaidang,using numerical simulation methods and remote sensing Technology,using the SHAW model to explore the temporal and spatial changes of groundwater level changes on the surface energy balance components on the site scale,and apply the SEBAL model to study the relationship between the surface energy balance components and groundwater on the regional scale
