The effects of elevated CO2 and N fertilization on chemical properties and turnover rates of soil organic compound were investigated. Elevated CO2 increased concentration of organic compounds in the soil. Higher rate of N fertilization also increased organic N compounds. Elevated CO2 and higher N input may improve soil fertility by increase of easily-decomposable organic matter.Carbon turnover rates of phenolic acids in the soil were affected with CO2 concentration markedly, but they were little affected with rate of N fertilization. As phenolic acids, phenol, Vanillin, 4-Hydroxybenzoic acid, Vanillic acid, Acetovanillone, Syringaldehyde, Syringic acid, Ferulic acid were detected. Ether-linked phenolic acids showed higher turnover rate than Ester-linked one.

研究了CO2和氮肥浓度升高对土壤有机质化学性质和周转速率的影响。CO2浓度升高增加了土壤中有机化合物的浓度。施氮量的增加也增加了有机氮化合物的含量。CO_2浓度升高和氮肥用量增加可通过增加土壤易分解有机质提高土壤肥力，土壤酚酸类物质的碳周转速率受CO_2浓度的影响显著，而受氮肥用量的影响较小。酚酸类物质中检测到苯酚、香草醛、4-羟基苯甲酸、香草酸、乙酰香草酮、丁香醛、丁香酸、阿魏酸。醚连接的酚酸比酯连接的酚酸具有更高的周转率。
