Fig. 7

a The aridity of the study area. b Spatial pattern of the change in LAI. c Spatial pattern of changes in precipitation, VPD and soil moisture. d Spatial pattern of ecological restoration programs. In (b), * indicates a significant change trend of LAI. In (c), PRE, VPD, and SM represent the change trends of precipitation, VPD and soil moisture, respectively. The “+” indicates an increasing trend of hydrological variables and “−” indicates a decreasing trend of hydrological variables. The subareas “i”, “ii”, and “iii” indicate the western Xinjiang, the northwestern Loess Plateau, and the southern Loess Plateau, respectively.
