Spatial patterns of the correlations between Normalized Difference Vegetation Index (NDVI) and T_max or T_min during the growing season (April–October) in the Yellow River Basin, 1982–2015. (a) Mapping of the partial correlation coefficients between NDVI and T_max, given that the corresponding T_min and precipitation are controlled for in the calculation. (b) Spatial distribution of significance level of the partial correlation coefficients between NDVI and T_max. (c) The partial correlation coefficients between NDVI and T_min by controlling T_max and precipitation. (d) Spatial distribution of partial correlation coefficients between NDVI and T_min.(I: Longyangxia in the upper reaches; II: Longyangxia to Lanzhou; III: Lanzhou to Hekou town; IV: Longmen to Sanmenxia; V: Inflow zone; VI: Hekou town to Longmen area; VII: Longmen to Huayuankou; VIII: below Huayuankou in the lower reaches).
