In this study, we expanded the potential use of the greenness index derived from digital camera imagery by accurate descriptions of phenology and canopy development in ecosystem models can produce reasonable carbon budgets at regional model based on canopy greenness data obtained from digital photography and on CO2 flux measured from eddy covariance towers might no attempts have been made to use digital camera imagery to monitor crop phenology and optimize carbon dioxide flux models in China.	./cache/work_clft6abfj5antdkzebrhfmuyk4.pdf	./txt/work_clft6abfj5antdkzebrhfmuyk4.txt
