摘要: 为了探讨太行山低山丘陵区林型和坡位对表层土壤有机碳(SOC)和全氮(TN)含量的影响,本试验研究了侧柏、栓皮栎人工林和撂荒地(对照)表层(0~20 cm)土壤SOC和TN含量的分布特征.结果表明: 同一林型或坡位条件下,土壤SOC和TN含量均呈现随着土层的加深逐渐下降的趋势.不同坡位条件下,表层土壤SOC和TN含量在有林地(栓皮栎、侧柏)均呈现坡上>坡中>坡下的趋势,在撂荒地则呈现坡下>坡上>坡中的趋势.不同林型条件下,坡上、坡中SOC和TN含量整体呈现栓皮栎人工林>侧柏人工林>撂荒地的趋势,坡下SOC和TN含量整体呈现出撂荒地最大的趋势.C/N值在上坡位和中坡位呈现出栓皮栎人工林>侧柏人工林>撂荒地的趋势,在下坡位呈现出栓皮栎人工林>撂荒地>侧柏人工林的趋势;同一林型条件下,不同坡位C/N存在差异,但不显著.表明太行山低山丘陵区栓皮栎人工林的适应性最强.

Abstract: To explore the effects of forest types and slope positions on the content of soil organic carbon (SOC) and total nitrogen (TN) in the lower hilly area of Taihang Mountains, we examined the distribution pattern of SOC and TN contents in Quercus variabilis plantation (Qo), and Platycladus orientalis plantation (Po), and abandoned land (Al). The results showed that in the same forest type or slope position, the contents of SOC and TN gradually decreased with increasing soil depth. Under different slope conditions, the contents of SOC and TN showed the tendency of upper-slope (U) > middle-slope (M) > lower-slope (L) in the planted forests (Qo and Po), but showed the tendency of L>U>M in Al. Under different forest types, the contents of SOC and TN in the U and M showed the trend of Qo>Po>Al. At the LS, the contents of SOC and TN of Al were the highest. The C/N ratio followed an order of Qo>Po> Al at U and M, while Qo>Al> Po at L. Within the same forest type, C/N of different slopes was different, but not significant. Our results suggested that the adaptability of the Qo plantation is the best in the lower hilly area of Taihang Mountains.
