The research on the vegetation phenology evolution and its driving forces are of critical importance for the eco-system, global meteorological and hydrological processes. Meanwhile, it is a highlighted topic in the meteorological hydrology and eco-hydrology community. Based on the review of the progress made on the vegetation phenology observation and phenological model research based on the in-situ observation and remote sensing, the main challenges of the remote sensing based phenological modeling research were summarized. Then, the suggestions and prospection were proposed as follows; (1)carry out the research based on both the hydrological and large scale phonological models; (2)investigate quantitative methods to evaluate the control of environmental factors; (3)develop phenology predicting models.
