摘要
杭州市城市土壤有机碳具明显的积累并具较大的空间变异性,城区土壤表土(0~10cm和0~100cm深度土壤平均有机碳贮量约为远郊区土壤的4.3和5.7倍。城市土壤有机碳中含较高比例的碳黑、颗粒态碳和较低比例的易氧化态碳,表明城市土壤有机碳较为稳定。随着人为影响程度的增加,土壤碳黑、颗粒状碳量增加,易氧化态碳的数量减少。
Urban soils in the Hangzhou city were significantly enriched with organic carbon. The organic carbon storages in surface layer (0~10cm depth) and 0 ~ 100cm depth of the urban soils were 4.3 and 5.7 times of those in suburban duration of human influence on the soils increases, concentrations of black carbon, and particulate organic carbon in the soils tend to increase, and those of active carbon tend to decrease.
