By comparing the matrices of the changes between 2000, 2005 and 2010, we find that China's carbon emissions decreased over the nearly decade-long period of rapid economic development in the face of climate change and the Kyoto protocol, which delineated each country's emissions reduction tasks. China has increased AZD-4547 saving and passed emission reduction acts and has developed related policies to guide and promote these policies; in particular, the eastern coastal provinces have reduced their carbon emissions through technology introduction and enterprise structure adjustment. Although their ESIs and EEIs in China vary based on economy and afforestation, the four groups are basically stable, which indicates that China's national reform policy and afforestation effects are basically the same across the provinces.
This article described the calculation of corresponding periods of ecosystem carbon sinks using land cover data in 2000, 2005 and 2010 extracted from time-series remote sensing data by supervised classification, followed by calculation of the ESI, EDI, EEI using a 3E model combined with statistical data to analyze spatial pattern differences and the changes in China's carbon emissions over ten years. The conclusions are that the Y3E values of half of China's provinces and autonomous regions are greater than 1, which indicates that the carbon emissions in these areas over nearly a decade are benign overall in terms of ecosystem circulation and that there is fairness and economic efficiency of carbon emissions. That the Y3E values in Beijing, Zhejiang and Gansu in 2010 are close to 1 indicates that most of China's coastal provinces are moving in a low-carbon, ecologically favorable and high-efficiency direction, as they are influenced by China's low carbon economic policy.
