| Abstract: | Insufficient water resources is a major constraint on sustainable development of agriculture and socio-economy, and an imminent threat to national food security. Present situation attached particular importance to assurance of water supply for agriculture and ecology, which was on the basis of effective predication for regional evapotranspiration and water use efficiency (WUE). In this paper, an evapotranspiration and gross primary production (GPP) model based on vegetation index from Terra-MODIS was develo... |
