This paper adopted the soil distribution area, sampling data and soil organic content from the first soil general survey and applied the technique of GIS to estimate soil carbon reservior in China.

根据中国第一次土壤普查得到的土壤各类型分布面积、采样数据、土壤有机质含量，运用GIS技术，来估算土壤碳库。

The content of soil organic matters is different in different ways of land use.

不同的土地利用方式下，土坡的有机质含量是不同的。

And under the same temperature and moist condition, the relatively value of CO2 released rate was increasing with the soil organic carbon content.

相同温度与土壤水分条件下，CO2排放速率相对值大小随土壤有机碳含量增加而增加。

Lehmann, the lead author of the paper which is published in the journal Nature Geosciences, said that the black carbon content of soils in the study ranged from zero to 82 percent of soil organic carbon.
