From the analysis of the mechanism of foliage phenology using remote sensing technology, we can see that vegetation index（VI） can indicate features of each phenophase. Many researches on the starting and ending days of the growing day, changes of florescence, changes of GPP , the sink and source of global carbon using vegetation index have been done. And all the above studies inside and outside speed up enlarge the fields of foliage phenology. On the other hand, the analysis on foliage phenology can improve the accuracy of vegetation classification and crop estimation. At the same time the advances of foliage phenology can speed up the development of hyperspectral remote sensing technology, too. The applied fields of phenology have been from the traditional fields of agriculture and forestry to the fields of phonological observations using remote sensing and ecological applications in the last 20 years in China. And studies on the spatial and temporal raw of the starting and ending days of the growing days, seasona changes of plants using remote sensing, changes of florescence using remote sensing, physiological and ecological characteristics of foliage, phenophase observations using hyperspectral remote sensing technology, educating children and the general public on phenology and global change issues should be done in the future in China. And the future of phenology is very splendid in China.
