Abstract
Based on SPOT VEGETATION NDVI time-series data, multi-phase China’s land use / land cover (LULC) data were extracted in this study, where land use degree method and land dynamic degree method were used to analyze the spatial and temporal change characteristics of China’s LULC in the latest decade. Moreover, bookkeeping model was applied to analyze the response of China's carbon sink to LUCC. Research conclusions were achieved as follows. China's annual vegetation carbon sink was 0.22- 0.32PgC/year, equivalent to 26% -28% of China's industrial CO2 emissions over the same period. Dynamic changes in woodland and grassland led to carbon sink changed in 11.4-15.7TgC, and the increased carbon sink due to LUCC offset 1.3-1.4% of China’s industrial CO2 emissions.
