| 摘 要： | 土壤有机碳是地球表层系统中最大且最具有活动性的生态系统碳库之一。我国农业土壤尤其是稻田土壤有机碳库的变化及其对陆地生态系统和大气CO2的源汇效应,对水环境质量和土壤肥力的影响,以及其在人类利用和管理与生态环境演变中的动态变化越来越受到重视。讨论了稻田土壤与旱地土壤有机碳固定的差异、有机碳在稻田土壤中分布、碳固定的可能机制及其施肥影响,并为进一步研究提出了展望。

| Abstract: | Soil organic carbon(SOC)has been shown as one of the largest and most mobile carbon pools of the earth surface ecosystem.For the last decade,in China,increasing attention has been given to the SOC pool(especially in paddy soils)change in relation to the sink or source effect of air CO2,to the water quality,to the soil fertility,and to the dynamics under global change scenarios.In this paper,the issues of paddy soil carbon sequestration differences from dry land,organic carbon distribution,mechanism of soil carbon sequestration,its fertilization factor and prospect researches were discussed. |
