Shuitu Baochi Xuebao, 2003 选择松嫩平原西部盐碱化程度最高的大安市叉干镇明乐村,研究碱斑地的蒸散过程、土壤水分入渗过程,以及盐分运移和水盐平衡规律,进一步探讨该地区盐渍荒漠化的形成机理。结果表明:碱斑地没有植被覆盖,蒸散过程以土壤蒸发为主,水分运动带动盐分大量向土表积累;碱斑地土壤水分入渗率低,下行盐分远远小于上行盐分。土壤表层盐分累积的结果,使得该地区的草地景观退化,碱斑地面积增加,导致盐渍荒漠化程度加剧。

基于ArcGIS空间插值的河套灌区土壤水盐运移规律与地下水动态研究
Shuitu Baochi Xuebao, 2021 为探明河套灌区盐渍化半封闭小型灌域作物生育期土壤盐分和地下水变异规律，选取巴彦淖尔市五原县盐渍化土壤典型区域作为研究区。采用区域土壤—地下水信息定点监测法，选取149个采样点，30口地下水观测井，获得各项指标数据，并结合经典统计学、空间插值、相关性回归分析等方法，研究了土壤盐分及地下水动态空间变异性、不同深度土壤空间变化特征及其与地下水埋深相关性。结果表明：4—10月各土层土壤含盐量平均降幅为5.53%，研究区1 m深土壤处于脱盐状态，耕作层土壤盐分向深层土壤运移。地下水埋深主要影响因子为引黄灌溉水量 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

Gongye shui chuli, 2023 随着我国工业化进程的加快，高盐废水的排放量也与日俱增。在双碳背景下，高盐废水的资源化不仅要求对水资源进行利用，还要求对废水中的盐分（主要是NaCl和Na2SO4）进行分离和资源化利用。系统归纳了高盐废水处理中的几种混盐分离技术，包括传统的变温结晶分盐和纳滤分盐，以及近年来研究人员广泛关注的选择性电渗析法（SED）分盐、电容脱盐法（CDI）分盐等电化学方法，以期为实际生产过程中选取适宜的高盐废水资源化手段提供一定借鉴。分析表明，传统方法具有低成本、技术成熟的优点，但也存在高能耗、膜污染等弊端 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Nickel‐based materials are highly remarkable as promising transition metal catalysts for the electrochemical hydrogen evolution reaction (HER) in alkaline electrolytes. However, their electrochemical performance is limited by an unfavorable d‐band energy (Ed) level. Herein, we showcase an effective lattice‐strain strategy to modulate the Ed of

New Phytologist, Volume 251, Issue 1, Page 207-227, July 2026.Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.
