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.

Distribution Characteristics of Phosphor and Sulfur in Different Wetland Soils of the Yellow River Delta [PDF]
, 2010 以黄河口滨岸潮滩湿地为研究对象,研究了不同植被群落覆盖下湿地土壤中磷、硫的变化特征及其储量状况。结果表明,植被群落的变化能够影响土壤中磷、硫的含量,但影响程度不同。沿植物群落演替方向,土壤全磷含量差异不显著,变异系数较小,而全硫含量受影响显著,呈“S“型波动变化;在垂直分布特征方面,全磷的差异程度不大,表明土壤中磷含量主要取决于成土母质,相对而言,硫的垂直分布特征存在较大差异,大部分采样点的变异系数在10%以上,属中等变异,其分布特征主要受制于土壤有机质的分布 ...
