A review on research of land surface water and heat fluxes
地表水热通量研究进展

Many field experiments were done, and soil vegetation atmosphere transfer(SVAT) models were stablished to estimate land surface heat fluxes. In this paper, the processes of experimental research on land surface water and heat fluxes are reviewed, and three kinds of SVAT model(single layer model, two layer model and multi layer model) are analyzed. Remote sensing data are widely used to estimate land surface heat fluxes.Based on remote sensing and energy balance equation, different models such as simplified model, single layer model, extra resistance model, crop water stress index model and two source resistance model are developed to estimate land surface heat fluxes and evapotranspiration. These models are also analyzed in this paper.
