Satellite remote sensing is the most effective means of monitoring the vegetation dynamic over large-scale. With the development of remote sensing technology in China, domestic Fengyun satellites has been gradually applied to the study of vegetation change. However, the performance of Fengyun satellites in depicting the vegetation dynamic is still unclear. The spatial and temporal consistency of normalized difference vegetation index (NDVI) products retrieved from FY-3C VIRR (FY-3C) and Terra MODIS (MODIS) was compared over Hunan and Jiangxi provinces. The results showed as follows. High consistence in spatial distribution and temporal dynamic (i.e., annual, seasonal, and monthly) are characterized by FY-3C and MODIS NDVI products. Regional averaged annual mean NDVI of Jiangxi province is higher than that of Hunan province. The annual mean NDVI of 2018 is higher than that of 2017 and 2019 in both FY-3C and MODIS NDVI products. Three years regional averaged annual mean NDVI in Hunan and Jiangxi Provinces based on MODIS (0.58) is 60% higher than of FY-3C (0.36). FY-3C NDVI is lower than that of MODIS NDVI in all seasons with the largest difference occurred in winter. MODIS NDVI (0.42) is twice higher than FY-3C NDVI (0.21) in winter and this magnitude is about 50% in the rest seasons. The monthly variation of FY-3C NDVI and MODIS NDVI is also consistent. The difference is stable and small in annual maximum NDVI but larger in annual minimum NDVI (the annual minimum NDVI based on MODIS is about 100% higher than that of FY-3C). Scientific reference for the ability of domestic Fengyun satellites to detect vegetation dynamic characteristics in typical areas is unraveled in this study.
