Shuitu Baochi Xuebao, 2016 为探明红壤坡地枯落物敷盖的保水作用及其机理，在江西省北部德安县第四纪红黏土母质发育的红壤坡地开展定位试验，以裸露坡地为对照，研究枯落物敷盖措施实施15 a后对0—60 cm土层土壤的持水性、供水性和水分有效性的影响。结果表明：赣北红壤坡地的土壤水分持水能力低，供水能力弱，有效水含量少，仅为9.0%～11.1%；枯落物敷盖处理的红壤坡地（0—30 cm）土壤持水能力高于裸露坡地；低吸力范围（＜100 kPa）枯落物敷盖处理的下层（30—60 cm）土壤供水能力高于裸露坡地 ...

Shuitu Baochi Xuebao, 2021 为探究微塑料对土壤持水性能的影响，选用粒径为1 mm和25 μm的聚乙烯微塑料（PE—MPs）颗粒进行土培处理后，采用高速离心机法测得不同处理下的土壤水分特征曲线，并使用Gardner模型进行拟合分析。结果表明：（1）土壤中累积少量的PE—MPs （0~5.00 g/kg）能增强土壤持水性，但当累积量超过一定阈值（5.00~50.00 g/kg）会导致土壤持水能力显著降低。（2）1 mm大粒径PE—MPs大量积累对土壤持水性的降低效应更显著；25 μm小粒径PE ...

Shuitu Baochi Xuebao, 2023 为探究大气氮沉降增加导致的土壤团聚体结构变化规律及其对土壤水分入渗性能的影响,在贡嘎山针叶成熟林和中龄林内分别设计2种氮肥形态[(NH4)2SO4、KNO3]和4个浓度水平(0,10,20,40 kg/(hm2·a)N)的添加试验,研究不同形态大气氮沉降对亚高山森林土壤团聚体结构和土壤水分入渗特征的影响。结果表明:(1)随施氮量增加,中龄林土壤大团聚体含量逐渐增加,土壤持水量、孔隙度和水分稳定入渗率逐渐增大;成熟林土壤大团聚体含量、土壤持水量、孔隙度和水分稳定入渗率均表现出先增加后降低的趋势;(2 ...

World Water Policy, Volume 12, Issue 2, May 2026.ABSTRACT Managed aquifer recharge (MAR) is presented as a water management approach that fits well within the broad sustainability agenda. Three European MAR projects' outcomes were analyzed to assess how these projects interpret sustainability. This article argues that MAR projects are pushed to a narrow interpretation of sustainability by funder ...

Functional Ecology, Volume 40, Issue 5, Page 1415-1427, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildfires are disrupting and regenerating forces in nature that affect all ecosystem components. However, the impact of wildfires on soil multitrophic biodiversity and the resulting consequences for ecosystem multifunctionality (EMF) remain poorly understood.
