| 摘 要： | <正>由温室气体排放导致的气候变化是当前全球关注的热点问题之一1]。化石燃料燃烧、水泥生产、土地利用变化等人类活动向大气中排放大量CO2,进而引起全球变暖和地球系统碳循环过程的显著变化。研究表明,大气CO2浓度已由1870年的280μmol mol-1增加至2005年的379μmol mol-1,目前仍以1.9μmol mol-1a-1的速率急剧攀升;同期地表温度平均增加了0.74℃(变幅0.56~0.92℃)2]。根据《中国应对气候变化国家方案》

| Abstract: | The study is to simulate the atmospheric CO2 concentration on soil dissolved carbon , to clarify the dynamic variation of the farmland ecosystems of the North China Plain soil carbon under the conditions of future atmospheric CO2 concentration. The project is based on the Beijing Changping beans wheat rotation system of free air CO2 concentration enrichment (FACE) reach platform, The wheat and bean used as the material to study the variation of dissolved carbon in wheat-bean rotation system under atmospheric CO2 concentration enrichment and nitrogen addition.SThe results of the research show that the CO2 concentration enrichment and nitrogen input in the short term did not significantly change the solubility of soil carbon profile change. In addition, CO2 concentration enrichment and nitrogen input led to significant seasonal variations in dissolved carbon content. Under the condition of CO2 concentration enrichment, a low dose of nitrogen will significantly reduce soil soluble carbon content. Giving the reasons that under the current soil nitrogen nitrogen levels, it is difficult to meet the demand of the context of future atmospheric CO2 concentration, soil microbial. |
