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.

封育和水平沟生态恢复措施对宁夏黄土丘陵区典型草原土壤生物学特性的影响
Shuitu Baochi Xuebao, 2017 研究禁牧封育和水平沟生态恢复措施下黄土丘陵区典型草原土壤生物学特性变化，以期为该区草地生态建设提供依据。采用空间梯度代替时间梯度的方法，在宁夏黄土丘陵区典型草原，选取未封育（放牧）、封育3～15 a、水平沟整地后1～15 a的土壤，分析0—10，10—20，20—30，30—40 cm土壤微生物数量、微生物生物量碳、量氮和土壤酶活性的变化特征及其相关性。结果表明：（1）试验区土壤微生物类群以放线菌为主，达到86.18%～4.43%，数量表现为放线菌>细菌>真菌；土壤微生物总数、细菌和放线菌数 ...

添加莠去津的土壤中微生物生物量碳、氮、磷对外源有机无机物质的动态响应
Shuitu Baochi Xuebao, 2004 研究了添加有机、无机营养物质对外加除草剂莠去津土壤(每1g土中含莠去津10mg/)中微生物生物量碳、氮和磷的动态变化过程。研究结果表明,在整个培养过程中,仅加莠去津的土壤中微生物生物量碳、氮、磷的含量均显著降低,与对照相比,分别平均降低了13.5%,10.1%,20.0%。但是,施用有机、无机营养物质的处理,土壤微生物生物量碳、氮、磷的含量均显著增加。不同处理对微生物生物量碳、氮的含量影响程度依次为:腐熟猪粪>紫云英>水稻秸秆腐熟猪粪>N、P肥配施>单施N肥>单施P肥。而对微生物生物量磷含量的影响则为 ...
