摘要:

卫星遥感在研究青藏高原非均匀地表区域能量通量和蒸发(蒸散)量时有其独到的作用。本文介绍了基于NOAA-14 AVHRR和Landsat TM资料推算藏北高原地区区域地表特征参数、植被参数及区域地表热通量的方案,并把其用于GAME/Tibet(全球能量水循环之亚洲季风青藏高原试验研究)和CAMP/Tibet(“全球协调加强观测计划(CEOP)亚澳季风之青藏高原试验研究”)试验区。并指出了此方法估算青藏高原非均匀地表区域地表能量通量和蒸发(蒸散)量时存在的难点问题和解决问题的可能途径。

Study on the Regional Land Surface Heat Fluxes over Heterogeneous Landscape of the Tibetan Plateau Area
Abstract:

For studying on the regional land surface heat fluxes over inhomogeneous landscape of the Tibetan Plateau area,the utilization of satellite remote sensing is indispensable.In this study,methods based on NOAA-14 AVHRR and Landsat TM are introduced and tested for deriving the regional land surface variables,vegetation variables and surface heat fluxes over inhomogeneous landscapes of the GAME/Tibet(GEWEX(Global Energy and Water cycle Experiment) Asian Monsoon Experiment on the Tibetan Plateau) area and the CAMP/Tibet(CEOP(Coordinated Enhanced Observing Period) Asia-Australia Monsoon Project(CAMP) on the Tibetan Plateau) area.Difficulties on the determination of regional land surface heat fluxes over heterogeneous landscape of the Tibetan Plateau by using the methods are introduced and the solving way to the difficulties is also proposed in this paper.
