  1. Note: GPP and HC were the abbreviations of gross primary productivity and human returned carbon, respectively. ER, CRC, ERC, and Ewat were the abbreviations of ecosystem respiration, carbon removal from cropland, emission from reactive carbon, and emission from water erosion, respectively. Portion was calculated as the ratio of each flux to the total carbon input, which was the sum of GPP and HC. MODIS was the abbreviation of Moderate Resolution Imaging Spectroradiometer data.
