淤地坝对坡地土壤有机碳分布的影响
Effect of Check-dam on Distribution of Soil Organic Carbon in Slope Land
摘要
Abstract
In order to explore the effect of check-dam on the distribution of soil organic carbon ( SOC) in slope land, the au-thor tested the SOC content in the slope land inside and outside check-dam of the Liudaogou basin.The results showed that the check-dam, which was built 20 years ago, could significantly increase the content of SOC in 0~130-cm-deep soil layer of 10-m-long inside slope land, especially the SOC content in surface soil layer was increased by 2.92 g/kg or 358.34%, which was very significantly different from that in surface soil layer of outside slope land ( P<0.01) .Basically, the SOC content in slope land ex-hibited a linear increasing trend from the outside to inside of check-dam, but the maximum value appeared near the boundary of inside dam.The existence of check-dam caused that the inside slope land had more SOC content than the outside one in the same slope position, and the biggest increase rate (117.36%) of SOC content was found in upslope position.The variation coefficient of SOC content in inside slope land was higher than that in outside one .关键词
