Contribution of Different Processes in Wetland Soil N_2O Production in Different Restoration Phases of the Yellow River Estuary, China [PDF]
, 2014 采用时空替代法,选择黄河口生态恢复前后未恢复区(R_0)、2007年恢复区(R_(2007))和2002年恢复区(R_(2002))的芦苇湿地为研究对象,分析了生态恢复工程对湿地土壤N_2O产生不同过程与贡献的影响. 结果表明,尽管不同恢复阶段湿地土壤N_2O总产生量差异明显,但总体均表现为N_2O释放. 恢复区湿地土壤的N_2O产生量大于未恢复区.
