摘要: 介绍了当前国内外地表水热通量观测研究的进展及3种不同类型的土壤植被大气传输模型(SVAT):单层模型、双层模型和多层模型.遥感手段常用于监测大面积地表水热通量.基于地表能量平衡方程,现已建立了许多遥感模型以估算水热通量(如简化模型、单层模型、附加阻抗模型、作物缺水指数模型和二源阻抗模型等),并对这些模型复杂程度及应用范围进行了分析.

Abstract: 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 SVATmodel(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.
