Short summary
To simulate grassland NPP in Southern China, a new model was built and validated based on data recorded from 2003 to 2014. There was a highly significant correlation between simulated and measured NPP. The NPP values had a decreasing trend from east to west and south to north. Mean NPP was 471.62 g C m−2 from 2003 to 2014. Additionally, the mean annual NPP presented a rising trend, increasing 3.49 g C m−2 yr−1.
