Abstract: Ecosystem carbon sinks can offset part of the carbon emissions from human activities, playing a significant role in the carbon neutrality process. Clarifying the relationship between carbon emissions and ecosystem services is crucial for achieving the dual goals of carbon neutrality and ecological environmental protection. Effective ecosystem management is a prerequisite for controlling carbon emissions, as well as for ecosystem conservation and restoration, making a significant contribution to emission reduction and the enhancement of ecosystem services. Therefore, this study takes Guangdong Province as an example, starting with ecological functional zones—units that can enhance the effectiveness of ecosystem management—combining multi-source data and localized methods to develop annual carbon emissions (CEs) and ecosystem service value (ESV) data from 2000 to 2020, and reveals the spatiotemporal relationships between CEs and the ESV. The results showed the following from 2000 to 2020: (1) The net CEs increased from 203.73 to 482.80 million tons, representing an increase of 279.07 million tons, or 136.98%. The metropolitan residential security zone (MRSZ) was the dominant carbon source area, accounting for more than 60% of the total net CEs. (2) The total ESV gradually decreased from CNY 596.95 to 504.56 billion, representing a decline of CNY 92.39 billion, or 15.48%. The WCZ had the highest ESV, accounting for more than 50% of the total in all periods. (3) Temporally, the net CEs were negatively correlated with the total ESV in the study area, especially in the MRSZ, while a positive correlation was observed in the agricultural products provision zone (APZ). Spatially, the main clusters were Low–Low and High–Low clusters, primarily distributed in the APZ and MRSZ. This study explores and reveals the spatiotemporal relationship between CEs and the ESV, providing valuable references for related research in Guangdong Province and other regional comparative studies.
