广州地表能量通量研究

Study on Land Surface Energy Flux in Guangzhou

以广州市为研究区域,利用1990和2006 TM数据以及2000 ETM+数据,借助SEBAL模型反演的地表温度以及地面气象站点数据得到了研究区地表显热及潜热能量通量。这除了对非渗透表面与地表能量通量各分量之间关系的研究具有必要性意义外,对于具有复杂地表的城市的能量蒸散发研究也有重要意义。

This paper taking Guangzhou as study area,using 1990 and 2006 TM data,2000 ETM ＋ data,with SEBAL model inversion of surface temperature and ground meteorological data,the study area＇s land surface energy flux were obtained.It not only had necessity significance to study the relationship among each component of non-porous surface and land surface energy flux,but also had significance to study energy evapor-transpiration of city with complex surface.
