Fig. 4From: Precipitation mediates the temporal dynamics of net primary productivity and precipitation use efficiency in China’s northern and southern forestsResponses of net primary productivity (NPP) and precipitation use efficiency (PUE) to variations in annual mean precipitation (AMP) and annual mean temperature (AMT) across China’s northern and southern forests. Graphs a and b represent responses of NPP and PUE to AMP, respectively. Graphs c and d response of NPP and PUE to AMT, respectivelyBack to article page
