| 摘 要： | 对黄土高原子午岭油松林不同管理方式下土壤的黑碳(BC)、有机碳(POC)和活性有机碳(LOC)的空间分布和积累进行了研究.结果表明,各种管理方式的油松林其POC、LOC和BC由表层至下层均呈显著的降低规律性.各种管理方式油松林0～10cm土层以BC>POC>LOC,10～20 cm土层中,天然油松林和粗放管理型油松林B...

| Abstract: | Spatial distribution and the accumulation of BC,POC and LOC under different management modes of Chinese pine forest in the Ziwuling forest region of the Loess Plateau were investigated.The results indicate that there is a significant decreasing trend of BC,POC and LOC under different management modes of Chinese pine forest from its top layer to the lower layer.In the depth between 0~10 cm,there is a trend of BC>POC>LOC under all of management modes,as for the depth between 10~20 cm,there is a trend of BC>PO... |
