Description
Summary:•We assessed the multi-temporal vegetation dynamic trends based on time series NDVI and EVI data comparatively.•A remarkable increase was observed in annual and seasonal NDVI and EVI over the Qinba.•Larger areas of no significant change were obtained in EVI compared to NDVI, except summer.•The seasons of significant increase occurred varied for different vegetation types.•Inconsistency characteristics of future vegetation dynamic trend was stronger, especially detected by EVI. The Qinling-Daba Mountains region (Qinba) is an important geographical transitional zone across the north and south of China. To comprehensively understand the ecological transition in the Qinba over past two decades, this study assessed and predicted the spatiotemporal variations of vegetation comparatively, using 250-m time series MODIS NDVI and EVI products. From 2000 to 2019, remarkable increases were observed both in annual and seasonal NDVI and EVI (P
