[Spatial-temporal dynamics of grassland NPP and its driving factors in the Loess Plateau, China].

We estimated grassland NPP using CASA model in the Loess Plateau during 2000-2015 and further analyzed the spatiotemporal dynamics, stability and persistence of grassland NPP. The driving factors of grassland NPP were analyzed from four aspects, i.e.
