根据《江苏土壤》及近几年调查和分析资料,计算提出江苏省农地土壤耕层总有机碳储库为0.2Pg。50～70年代土壤有机碳有所下降,自80年代实行土壤改良以来,江苏土壤有机碳储截存总体上有增加的趋势,其土壤的碳(C)截存速率可达27～350 g/(m~2·a)。因此,经营管理良好的农业实践对于提高陆地系统碳截存有重要意义。 According to “Jiangsu soil” and recent years of investigation and analysis of data, calculated that Jiangsu Province farmland soil tillage total organic carbon pool is 0.2Pg. Soil organic carbon decreased from 1950s to the 1970s. Since the soil improvement in the 1980s, soil organic carbon storage in Jiangsu Province generally increased. The rate of carbon (C) sequestration in soils reached 27-350 g / (m ~ 2 · a). Therefore, well-managed agricultural practices are of great importance to enhancing the carbon sequestration of terrestrial systems.
