英文摘要	Achieving carbon neutrality is currently the most important and urgent task in the field of ecological environment for China. However, the ecosystems carbon stock dynamic, carbon sequestration potential and main driving factors in the economically developed regions of China, Jiangsu Province in recent 40 years are still unclear. Existential quantification scale and interactive human-land coupling relationship pose a great challenge to identify the carbon dynamics pattern in economically developed regions in China. In this study, we used scenarios simulation and main control factor analysis method to identify the spatiotemporal pattern of carbon dynamics in the developed Jiangsu region from 1979 to 2018, and defined and evaluated the sensitivity of different ecosystems to different environmental factors. Furthermore, we separated and quantified the individual and interactive response characteristics of carbon stocks to different environmental factors, and the results showed that Jiangsu has experienced rapid climate change (warming rate +0.5 degrees C/10a), and warming is a key climate factor leading to a decrease in soil organic carbon (SOC), and decreased by -30.7 g C/m(2) during the study period is greater than the promotion effect of precipitation (18.7 g C/m(2)).Vegetation carbon (VEGC) has no significant response to temperature and precipitation. The pattern of carbon dynamic shows significant spatial heterogeneity. On the whole, there is a trend of increasing carbon storage in coastal areas and decreasing carbon storage in urban agglomeration in southern Jiangsu. The factor analysis results indicate that the CO2 enrichment effect promotes the increase of carbon storage in different carbon reservoirs; The impact of climate change on different carbon pools mainly manifests as negative effects; The interactive effect is manifested as a positive effect, and the sensitivity of carbon stocks to the positive CO2 fertilization effect is greater than that to climate change. In the future, attention should be paid to the impact of double superposition of temperature increase and urban heat island effect on the carbon stocks of coastal wetlands and urban forest ecosystem in southern Jiangsu.
