水土保持措施对土壤物理性状的影响——以黄土高原水土保持世界银行贷款项目区为例
Shuitu Baochi Xuebao, 2003 通过对黄土高原水土保持世行贷款项目实施后土壤物理性状变化的分析,了解不同水土保持 措施对土壤物理性状的影响.结果表明,水土保持措施的实施,使砂壤土的物理性粘粒逐渐 增加,物理性砂粒相应减少,土壤容重降低,孔隙度增大,改善了土壤结构;同时以延河项 目区人工种草为例,经计算消除降水影响后,所得水保措施对土壤含水量的影响量达2.35% .

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 ...
