Effects of the mole fraction of elevated atmospheric CO2 on soil organic carbon stability

  • 摘要: 随着工业的不断发展,全球大气二氧化碳(CO2)呈明显增加趋势。大气CO2的增加将会影响土壤有机碳(SOC)转化和更新,进而改变土壤碳的稳定性。研究大气CO2升高对SOC稳定性的影响,不但是评价陆地生态系统对气候变化反馈效应的重要环节,也对实现碳元素在土壤中的有效储存,对保持土壤肥力的可持续性具有重要意义。利用现有的文献资料,综述了大气CO2升高对SOC稳定性的影响及其稳定性指标(生物指标、化学指标、其他指标等),外源氮和大气CO2升高的交互作用对SOC稳定性的影响,以及SOC稳定性随时间尺度的变化趋势等。总结发现:大气CO2升高导致活性有机碳(溶解性有机碳、颗粒性有机碳、易氧化有机碳等)比例增多,SOC稳定性降低,尤其在氮限制的环境中,SOC稳定性更差。总结近年的研究成果发现:随着高CO2处理时间的加长,SOC稳定性降低速率逐渐减小,表明土壤本身具有一定的适应能力和自我恢复能力。最后展望了SOC稳定性变化对植物生理、生长的反馈影响。未来大气CO2升高对SOC稳定性的影响研究,应该着力于提高农田生态系统土壤肥力可持续性,提高农作物的产量产能。图1参74

摘要: 随着工业的不断发展,全球大气二氧化碳(CO2)呈明显增加趋势。大气CO2的增加将会影响土壤有机碳(SOC)转化和更新,进而改变土壤碳的稳定性。研究大气CO2升高对SOC稳定性的影响,不但是评价陆地生态系统对气候变化反馈效应的重要环节,也对实现碳元素在土壤中的有效储存,对保持土壤肥力的可持续性具有重要意义。利用现有的文献资料,综述了大气CO2升高对SOC稳定性的影响及其稳定性指标(生物指标、化学指标、其他指标等),外源氮和大气CO2升高的交互作用对SOC稳定性的影响,以及SOC稳定性随时间尺度的变化趋势等。总结发现:大气CO2升高导致活性有机碳(溶解性有机碳、颗粒性有机碳、易氧化有机碳等)比例增多,SOC稳定性降低,尤其在氮限制的环境中,SOC稳定性更差。总结近年的研究成果发现:随着高CO2处理时间的加长,SOC稳定性降低速率逐渐减小,表明土壤本身具有一定的适应能力和自我恢复能力。最后展望了SOC稳定性变化对植物生理、生长的反馈影响。未来大气CO2升高对SOC稳定性的影响研究,应该着力于提高农田生态系统土壤肥力可持续性,提高农作物的产量产能。图1参74
