英文摘要Climate change affects soil organic carbon (SOC) and contributes to the uncertainty of terrestrial carbon sinks in the global carbon budget. The response of SOC to climate change and its associated control processes are still not well understood at the national level due to limited surface monitoring and control experiments. With changes in vegetation growth and the regulation of its carbon input, the feedback of topsoil SOC to climate change is likely to become more complex at broad geographical scales. Here, on the basis of the long-term satellite remote sensing data from 2000 to 2019, multiple linear regression and pathway analyses were applied to the raster scale to investigate the importance of vegetation carbon input relative to climate change impacts on topsoil SOC in China and quantify the direct effects of climate change on topsoil SOC and the indirect effects through vegetation net primary productivity (NPP). The results show that the overall trend of increase in topsoil SOC in China from 2000 to 2019 is significant (P < 0.05), and most regions show a good development trend in the future, except for some areas in the Central South, East, and Northeast regions, where a risk of degradation exists. Relative to climate change, the dominant areas of NPP impact on topsoil SOC in China occupy a considerable proportion, especially in the North, Northwest, and Central South regions, with area proportions of 68.15 %, 49.52 %, and 47.99 %, respectively. The indirect positive impacts of climate change on changes in topsoil SOC in China through vegetation carbon input offset the direct negative impacts in most areas. These results have important implications for enhanced prediction of future SOC changes and provide references for terrestrial carbon sinks management strategies in the context of response to climate change.
