Testing GLEAMS for Nitrate Leaching Modeling in an Agricultural Catchment of Southeast China [PDF]
, 2007 利用我国东南亚热带地区农业小流域不同土地利用方式的硝氮渗漏淋失实测数据检验了GLEAMS(Groundwater Loading Effects of Agricultural Management Systems)模型在该地区的适用性。通过现场试验和实地调查并结合模型手册,获取模型所需的水文和营养盐参数,参考模型参数的敏感性分析结果对模型进行调试。结果表明模型对水稻田除外的其它土地利用方式的硝氮渗漏淋失模拟效果较好。水稻田渗漏模拟效果差的主要原因在于模型的水分平衡方程不能反应水稻田长期淹水的实际情况 ...

Shuitu Baochi Xuebao, 2006 对青海大通北川河流域山地退耕还林不同配置模式的水文效应进行了研究，结果表明，不同配置模式植冠层截留量、枯枝落叶层的容水量、土壤总持水量随着林分植冠层生物量和枯枝落叶层现存量的增加呈上升趋势，同时，在林分总蓄水量中，土壤持水量所占比值较大（〉97％），而土壤稳渗速率随着土壤总孔隙度的增大而增大。其中：（1）在浅山区，植冠层截留量和枯枝落叶层的容水量以模式D（中国沙棘）最大，分别为1．43mm，1．87mm；土壤持水量和林分总蓄水量以模式C（青杨＋枸杞）最大，分别为327．88mm，329．07mm ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects
