土壤碳是碳循环中重要的环节,同时与土壤的理化指标存在着密切的联系.通过对长三角地区主要城市土壤和农田土壤的碳质量分数、主要化学组分、pH值、磁化率等主要土壤指标的统计,分析土壤理化指标对土壤总碳和有机碳的影响,讨论了其差异及形成原因.研究结果表明,城市CO2释放能力大于农田土壤.

Soil carbon is an important part of carbon cycle. It is also correlated with the soil proper- ties. Through detection of major soil parameters such as the total carbon (TC), major chemical composi- tions, pH, magnetic susceptibility of the urban and farm soils of the Yangtze River Delta Region, the study analyzed the influence of the physical and chemical properties on the total carbon and organic carbon (TOC) of soil, and the differences and causes for the differences were discussed. The study revealed that the urban soil has greater CO2 release potential than the farm soil.
