Exploring temporal dynamics in aboveground net primary productivity (ANPP) and their correlations to climatic variables in grasslands is significant to sustainable development of animal husbandry and ensuring food security and ecological security. Studies on the Inner Mongolian temperate grasslands and the Tibetan Plateau alpine grasslands have been widely reported. However, few researches on subtropical grasslands were reported in the past. It is still unclear how subtropical grasslands response to climate changes. In this study, we discussed the temporal dynamics in ANPP of grasslands in Yibin during 2000-2015 using simple and piecewise linear regressions. Correlations between ANPP and climatic variables were then analyzed using the partial correlation analysis. Our analysis indicated that (1) the multiyear average ANPP was recorded as 129.91g C m-2 yr-1 in grasslands in Yibin from 2000 -2015. The multiyear average ANPP was 130.48 g C m-2 yr-1 in temperate steppes and was 116.34 g C m-2 yr-1 in tropical herbosas, respectively. (2) ANPP exhibited an obvious increasing trend during 2000-2015. However, the increasing trend did not persist. ANPP trends significantly changed in 2007. (3) Temporal variations of ANPP were affected by temperature and precipitation together. Temperature and precipitation all had positive effect on ANPP variations. Temperature performed better than precipitation in explaining ANPP variations in grasslands in Yibin. Our research results were important for understanding mechanisms of ANPP response to climate changes in subtropical grasslands.
