Shuitu Baochi Xuebao, 2020 以青海省德令哈枸杞产区不同沟垄措施下的枸杞地为研究对象，以无覆盖平作枸杞地为对照（CK），在分析该地区降雨特征的基础上，研究了沟垄覆膜措施下不同沟垄比（30：32 cm，24：32 cm，18：32 cm，12：32 cm）对枸杞土壤含水率、产量及水分利用效率的影响。结果表明：（1）在年降水量不足300 mm的试验区，沟垄覆膜不同沟垄比种植相比于无覆盖平作种植土壤含水率、产量及水分利用效率显著升高，增产节水效果最优的GLBc （沟垄比18：32 cm）处理相比CK产量提高60.14%，耗水量降低7.47%

Rare Metals, EarlyView.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Rare Metals, EarlyView.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

Water Use Patterns of Coastal Wetland Plants in the Mangrove Wetlands of Zhangjiang Estuary and Their Ecological Significance [PDF]
, 2012 滨海湿地生态系统位于陆地与海洋交汇处，受海水周期潮汐的影响，其水文特征具有明显的空间异质性和时间变异性。虽然滨海植物生长在一个长期水淹环境中，水分对它们的生长却是一个限制因子，这是因为滨海植物除了受到氧气供给的限制和高盐分以外，还受到了因高盐分而造成的水分胁迫，具有典型生理干旱的特点。因此，水分来源及其有效性是影响滨海植物分布和生长的一个重要因素。 滨海植物由于受到潮汐水淹及盐度等环境因素的梯度影响，常呈现由海向陆的带状分布特征，以及沿河分布的特点。目前滨海湿地生态系统受到互花米草 ...
