Abstract

Carbon storage in terrestrial ecosystems and its changes have become the focus of research on climate and environmental changes, wherein forestland changes are the key driving factors affecting it. Studying the relationship between forestland change and carbon storage is helpful to better understand the impact mechanism of the ecosystem carbon cycle. Most of the previous studies in China have estimated a small area with different calculation methods, but the unified research method and standard for China's national research are lacking. This study takes China as a case study, we analyze the spatiotemporal change patterns of forestland and their impacts on carbon storage. The results show that the trends of forest land changes and its carbon storage are basically the same, which maintained an increasing trend. The regression analysis shows that China has increased the afforestation of artificial forests is the main reason. However, the increase of carbon storage in different regions was uneven, which was larger in regions with more afforestation and less logging, such as North China. This research is an important step in advancing China's goals of "Carbon Peaking" and "Carbon Neutrality”, and is also important for the understanding of the carbon cycle.
