| 摘 要： | 农田土壤碳库储量及固碳潜力是评估温室气体减排的重要依据之一.综述主要农田表土有机碳含量变化特征的研究进展,分析中国主要农田类型表土的同碳潜力.认为中国农田表土有机碳含量总体呈上升趋势;水田和旱地有机碳含量均有显著增加,但水田的固碳能力高于旱地,水田和旱地的固碳潜力因环境条件不同各有差异.提出要从固碳土壤学、固碳动力学上...

| Abstract: | Carbon storage and sequestration potential of a cropland soil are key factors in assessing emission reduction of greenhouse gas.In this paper,the carbon sequestration potential of croplands in China was analysed based on the topsoil's organic carbon content.Studies showed that the overall organic carbon content of the cropland topsoil in China was on the rise.In both paddy field and dry land soils,the organic carbon content increased significantly over the years.And,the capacity to sequester carbon dioxide ... |
