【摘要】Though many studies have focused on the causes of shifts in trend of temperature,whether the response of vegetation growth to temperature has changed is still not very clear.In this study,we analyzed the spatial features of the trend changes of temperature during the growing season and the response of vegetation growth in China based on observed climatic data and the normalized difference vegetation index (NDVI) from 1984 to 2011.An obvious warming to cooling shift during growing season from the period 1984-1997 to the period 1998-2011 was identified in the northern and northeastern regions of China,whereas a totally converse shift was observed in the southern and western regions,suggesting large spatial heterogeneity of changes of the trend of growing season temperature throughout China.China as a whole,a significant positive relationship between vegetation growth and temperature during 1984 to 1997 has been greatly weakened during 1998-2011.This change of response of vegetation growth to temperature has also been confirmed by Granger causality test.On regional scales,obvious shifts in relationship between vegetation growth
