Abstract

全球气候变化正在改变全球的降水格局,未来干旱和暴雨事件将会增多,进而加速土壤干湿交替现象的发生。土壤有机碳作为生态系统中最主要的碳贮存形态,很可能在干湿交替作用下发生改变。本文综述了近年来国内外有关土壤有机碳对干湿交替响应的研究,并从土壤结构和微生物活性变化两个方面阐述了干湿交替作用下土壤有机碳矿化的响应机理,最后分析了目前研究存在的不足与局限性,提出今后干湿交替条件下土壤有机碳矿化的研究方向及发展趋势,以便为全球变化背景下的土壤生态系统有机碳循环的预测和管理提供参考依据。

Other Abstract

Changes of global precipitation under climate change scenarios is altering the processes and frequencies of soil drying and wetting. Consequently, as the main storage form of soil carbon, organic carbon is more likely to be influenced by the frequent soil drying and wetting alternations. According to the recent studies on the response of soil organic carbon to alternate drying and wetting, the changes of soil structure and soil microbial activity are the two main mechanisms that can give strong effects on soil organic carbon mineralization by the drying and wetting alternations. Based on the deficiencies and limitations on the current researches, the further research directions and development trend in this area are discussed. This review will provide a reference for the prediction and management of soil organic carbon cycling under global changes.
