| 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(0~10 cm)和0~100 cm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。

| Abstract: | Urban soils in the Hangzhou city were significantly enriched with organic carbon.The organic carbon storages in surface layer(0~10 cm depth) and 0~100cm depth of the urban soils were 4.3 and 5.7 times of those in suburban area.The urban soils had higher p |
