Fig. 6. The correlative relationships of annual accumulative net ecosystem productivity (NEP, g C·m-2·a-1) with annual carbon use efficiency (CUE, A) and normalized difference vegetation index (NDVI, B) from 2004 to 2008. Hollow triangles represent the alpine shrub- meadow in Haibei (△) and hollow circles denote the alpine steppe-meadow in Damxung (〇). Adj.R2, adjusted coefficient of determination.
