根据第四次全国森林清查的122个样地和第二次全国土壤普查的388个土壤剖面数据，估算了东北地区植被和土壤的碳储量。地理信息系统（GIS）技术已被用于推断中国东北整个地区的植被和土壤有机碳的特定地点估计值。我们的估计表明，该地区植被和土壤的碳含量分别为 2.81 PgC (1015g C) 和 26.43 PgC，植被和土壤有机碳的面积加权平均密度分别为 22.7 MgC/ha 和 212.7 MgC/ha。该地区东部和北部地区的碳储存量远高于该地区其他地区。中国东北地区植被和土壤有机碳的巨大空间变化表明，对碳储量和通量的区域估计应考虑这些空间变化。我们建议所开发的方法可以用于整个中国以及世界其他地区。
We have estimated the stocks of carbon in vegetation and soil in northeast China based on data for 122 plots from the fourth national forest inventory, and for 388 soil profiles from the second national soil survey. The techniques of Geographic Information System (GIS) have been used to extrapolate site-specific estimates of vegetation and soil organic carbon to the entire area of northeast China. Our estimate indicates that the amount of carbon in vegetation and soil for the region are 2.81 PgC (1015g C) and 26.43 PgC, respectively, and that the area weighted average density of vegetation and soil organic carbon are 22.7 MgC/ha and 212.7 MgC/ha, respectively. The eastern and northern parts of the region show much higher carbon storage than the rest of the region. Substantial spatial variations in vegetation and soil organic carbon across northeast China suggest that regional estimates on carbon stocks and fluxes should take into account these spatial variations. We suggest that the methodology developed can be used for the entire nation of China as well as other regions of the world.
