Shuitu Baochi Xuebao, 2022 草地沙化是青藏高原草地生态环境恶化的显著问题之一，为研究不同恢复措施对高寒沙化草地植被与土壤的影响，以沙化草地（DG）、人工草本恢复草地（AG）、人工灌丛恢复草地（AS）以及天然草地（NG）为研究对象，基于植被群落和土壤特征的变化及两者的相互关系，评价了不同人工植被恢复措施对高寒沙化草地22年的恢复效果。结果表明：（1） AG和AS分别使DG的地上生物量增加至109.21，1 293.21 g/m2，但2种恢复措施的草本地上生物量均显著低于NG，而AG的植被群落物种丰富度比AS显著低31.48 ...

Shuitu Baochi Xuebao, 2020 旨在探讨不同植被恢复策略对土壤入渗特征空间变化的影响，通过对贵州石漠化治理试验区自然草灌木混合林、次生林地、退耕自然生草地、芒果地、坚果地及玉米地的土壤容重、土壤孔隙度、土壤有机质和土壤渗透特性的分析。结果表明：不同植被恢复策略下土壤容重、孔隙度和有机质含量存在显著差异，具体表现为自然植被恢复（草—灌木混合林和次生林地）和秸秆还田种植方式均能有效降低土壤容重，增加土壤孔隙度。随着土层深度增加，土壤容重呈增大趋势，土壤孔隙度和有机质含量变化趋势相反；植被恢复方式和土层深度显著改变了土壤的水分渗透特性 ...

Studies on Changes in Atmospheric Greenhouse Gas Fluxes from Soils of Kandelia obovata Mangrove Forests with the Development of Restored Vegetation in Jiulong River Estuary [PDF]
, 2014 选取福建九龙江口南岸浮宫镇霞郭村秋茄红树林研究断面，研究夏季白天的一个潮汐周期内未被潮水浸没时红树林土壤3种温室气体（N2O、CH4和CO2）通量变化情况，探究滩位和潮汐日变化对该地区红树林土壤大气界面温室气体通量的影响。在此基础上，以光滩为对照和恢复的起点，再选取26年生和50年生的人工秋茄红树林以及天然成熟林代表不同恢复阶段，探讨不同植被恢复阶段红树林土壤-大气界面这3种温室气体通量随植被恢复时间的关系，并分析植被恢复导致的土壤环境变化对温室气体通量的影响，为人工红树林的功能恢复提供参考依据 ...
