摘要

为了更好地理解土壤碳氮元素对氮添加的响应，通过短期原位模拟氮沉降试验，揭示黄土高原子午岭人工油松（Pinus tabulaeformis Carrière）林土壤碳氮对外源氮添加的响应过程和机制。从2015—2016年设置4个氮添加水平，分别为对照（0 kg/（hm2·a），N0）、低氮（50 kg/（hm2·a），N50）、中氮（100 kg/（hm2·a），N100）和高氮（200 kg/（hm2·a），N200），研究人工油松林地不同深度土层土壤有机碳和全氮以及土壤碳氮储量对模拟氮添加的响应。结果表明：土层对土壤有机碳、全氮和碳氮储量有显著影响，上层土壤有机碳、全氮和碳氮储量显著高于下层土壤；氮添加水平对土壤有机碳、土壤碳储量影响不显著，但可显著影响土壤全氮和氮储量。此外，土壤有机碳、全氮和碳氮储量和土壤碳氮储量比受地下生物量碳氮比的影响显著。因此，短期氮添加对人工油松林地土壤碳的影响不显著，但可显著影响土壤氮，地下生物量碳氮比是影响土壤碳氮的重要因素。

Abstract

To better understand the responses of soil carbon and nitrogen to the nitrogen addition

this paper revealed the response processes and mechanisms of soil carbon and nitrogen to exogenous nitrogen addition through a short-term simulated nitrogen deposition experiment in artificial Pinus tabulaeformis Carrière plantation in Ziwuling Mountain of the Loess Plateau. From 2015 to 2016

four nitrogen addition levels

including control (0 kg/(hm2·a)

N0)

low nitrogen (50 kg/(hm2·a)

N50)

medium nitrogen (100 kg/(hm2·a)

N100)

and high nitrogen (200 kg/(hm2·a)

N200)

were set up to study the responses of soil organic carbon(SOC)

total nitrogen (TN) and soil carbon and nitrogen storage (CS and NS) in different soil depths to the simulated addition nitrogen. The results showed that soil layer had significantly influence on SOC

CS and NS. SOC

CS and NS in the surface layer were significantly higher than those in the deeper soil layers. Nitrogen addition level had no significant impact on the SOC and CS

while significantly affected the TN and NS. In addition

SOC

CS and NS

and CS/NS were significantly affected by the carbon nitrogen ratio (C/N) of belowground biomass. Therefore

short-term nitrogen addition had no significant influence on soil carbon

but it could significantly affect soil nitrogen

and C/N of belowground biomass was the important factor affecting soil carbon and nitrogen.
