Abstract

Forest ecosystems play a key role in mitigating and adapting to climate change.A comprehensive understanding of the spatiotemporal trends in forest carbon stocks is essential for maintaining the regional carbon balance,predicting the potential of forest carbon stocks,adjusting conservation and management measures.Based on the three remote sensing datasets,forest carbon stock(FCS),land use cover change(LUCC)and digital elevation model(DEM),Mann-Kendall nonparametric test and correlation analysis methods were used to analyze the spatiotemporal trends of forest carbon stock and its response to land use change in Jiangxi Province from 2005 to 2020.The results showed that 1)forest carbon stock in Jiangxi Province showed an upward fluctuating trend,with an average annual growth rate of 12.59%,the minimum value appeared in 2009,which was 5.3×108tC,and the maximum value appeared in 2018,which was 6.5×108tC.2)The carbon stock is increasing in hilly areas in the central and southern parts,while it is decreasing in the lower-altitude northern parts.3)Jiangxi Province shows a decreasing trend in forest area but an increasing trend in forest carbon stocks,mainly due to urban expansion and continued sustainable forest management.4)Ecological protection and restoration measure is one of the main factors that promoting the stable increase of forest carbon stock in Jiangxi Province.In the future,the rich forest resources should be fully developed,and the synergistic efficiency of environmental protection,economic development,and poverty alleviation should be promoted through the development of Chinese Certified Emission Reduction(CCER) forestry carbon sink projects.

Key words： forestry carbon stock; Jiangxi Province; spatiotemporal characteristics; Mann-Kendall test; forest management
