Shuitu Baochi Xuebao, 2023 为分析气候变化及植被和淤地坝等生态建设措施对径流变化的影响,选取宁夏典型入黄流域清水河和苦水河为研究对象,采用Pettitt突变方法分析研究流域气象水文和生态建设措施等要素的变异点,基于Budyko理论,通过建立水热耦合控制参数与生态建设措施的多元线性回归方程,构建耦合生态建设措施下的降水-径流模型,并对模型进行适用性评估,采用弹性系数法,量化不同生态建设措施对径流变化的贡献率。结果表明:研究流域径流均呈减小趋势,且年径流突变均发生在2000年;水热耦合控制参数与NDVI和淤地坝指数呈显著的正相关关系 ...

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, Volume 8, Issue 7, Page 2186-2199, July 2026.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Because of superior transportability and high energy capacity, methanol is regarded as a potential hydrogen carrier. Photocatalytic methanol dehydrogenation offers a sustainable and cost‐effective method for releasing hydrogen. Conventional photocatalysts face challenging obstacles, including the low catalytic efficiency and rapid ...

Shuitu Baochi Xuebao, 2021 针对降雨和床面大糙度共同作用下坡面降雨径流侵蚀不平衡输沙特性研究薄弱的问题，采用室内模拟降雨试验的方法，研究不同降雨强度和坡长条件下的坡面降雨径流侵蚀输沙特性。结果表明：（1）坡面为裸坡、坡度为10°条件下，径流含沙量随坡长的增加呈增大趋势，当坡长由1 m增加至8 m时，同一雨强下径流含沙量增大3.28~7.15倍；径流含沙量随雨强的增大而增加，当雨强由40 mm/h增大至120 mm/h时，同一坡长下径流含沙量增加1.41~2.97倍。（2）分析降雨径流侵蚀条件下 ...

Recovering Critical Elements From Wastewater for Battery Materials: A Review
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

Shuitu Baochi Xuebao, 2004 通过对黄前库区流域森林主要类型刺槐林和油松林土壤结构状况和渗透性能的比较,研究了不同森林类型地表径流水的移动规律。在自然降雨后,以1m×1m为基本单位推算其可能产生的地表径流量,根据实际径流量推算地表径流水在径流过程中下渗的数量。研究结果表明:刺槐林的森林土壤结构相对较好,地表径流水下渗的速度较快,而流速较慢,因而产生的地表径流量较少;而油松林,特别是阳坡油松林的土壤结构较差,地表径流水下渗的速度较慢,而流速较快,因而产生的地表径流量较大。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This
