黄土高原子午岭油松林管理方式对黑碳和颗粒有机碳积累的影响
Effects of management mode of Chinese pine forest on accumulation of black carbon and particulate organic carbon in the Ziwuling forest region of the Loess Plateau
摘要
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>POC>LOC under natural Chinese pine forest and extensive management mode , but the trend in fine management mode presents POC>LOC>BC ; Furthermore , there is no significant difference of BC /TOC at each soil layer under both natural Chinese pine forest and extensive management modes , but the trend of BC /TOC under fine management mode presents decrease . Meanwhile , there is a decreasing trend of POC /TOC from the top layer to the lower layer under all the management modes of Chinese pine forest , but as for LOC /TOC , it presents an increasing trend .关键词
