| 摘 要： | 碳水化合物作为土壤有机质重要成分之一,一直被认为是较为灵敏的有机质示踪成分。在全球气候变化趋势下,CO2和O3浓度升高可改变植物群体组成,碳在地下生态系统的分配等最终间接地改变土壤化学特性。在未来大气环境变化趋势下,CO2和O3浓度升高对植物-土壤生态系统的影响已成为众多学者研究的热点问题,并取得了一定的成果,而对土壤有机质研究中作为重要指标和主要对象——碳水化合物的影响研究相对较少,为此综述了CO2和O3浓度升高对碳水化合物累积分布特征影响方面的最新进展,并提出今后开展研究的建议。

| Abstract: | Soil carbohydrates are a significant part and sensitive tracer of the soil organic matter.In global change trend,the studies on effects of elevated CO2 and O3 on plant-soil ecosystem become hotspot matter and obtain determinate harvest.However,few investigations focused on impact on soil carbohydrates.The newly progress in the effects of elevated CO2 and O3 on accumulation and distribution characteristics of soil carbohydrate are reviewed.Future systematic research in this field are also recommended. |
