摘要：
Crop water requirement is very important for water cycle and is a determinant factor for the accurate estimation of water and heat flux in the Soil-Plant-Atmosphere Continuum (SPAC). In arid regions, quantitative estimation of crop water requirement is the base of appraising terrestrial NPP, regional water consumption, soil water transport, crop production, and land use under changing climate. In this study, we selected the middle reaches of Heihe river basin as the study area and estimated the crop water requirement for 2009 use SEBS model, remote sensing data (MOD021KM , MOD03, MOD 09GA) and crop phenological data. We found that: 1) SEBS model performed well and can be used to estimate the spatial distribution of crop water requirement in the arid regions; 2) The corresponding results can provide baseline aimed to fulfill water requirement for crop production at middle reach and vegetation conservation at lower reach of Heihe River basin.
