RS-based Estimation of Evapotranspiration in the Yarkant Oasis
摘要
Abstract
In this paper, the values of latent heat flux were estimated for the Yarkant Oasis using the coupled algorithm of the harmonic analysis method, two-source energy balance （TSEB） model and MODIS data. The instantaneous evapotranspiration （ET） was extended to daily, monthly and annual scales. The spatiotemporal distribution of water consumption in the oasis in 2007 was analyzed. Water consumption proportions of different land use types were also calculated. In remote sensing method, though the surface energy balance was considered only, the differences between the simulated results of annual water consumption over the oasis and the values computed with water balance equation were low. Mean simulated annual ET results approximated to the values estimated with the runoff-evaporation hydrological model for all the land use types. The results reveal that the ET model used in this paper can be used for researching water consumption in oasis, and the estimated results can provide scientific basis for redistributing water resources in the Yarkant Oasis.关键词
