若尔盖高原高寒泥炭湿地水碳过程研究进展

Shuitu Baochi Xuebao
目的针对水土过程与碳流失过程耦合研究不足、长期连续观测数据缺乏、流域尺度水碳通量定量评估薄弱等问题，系统综述若尔盖高原高寒泥炭湿地水碳过程的研究进展，为湿地可持续管理与“双碳”目标提供科学依据。方法基于国内外若尔盖高原已有研究成果开展系统性文献综述，从地球关键带视角解析水-碳-生物多圈层耦合机制，阐明水文条件、植被演替与气候变化对碳循环的协同调控作用；同时，结合生态修复工程实践与政策演进历程，分析湿地保护技术（如复湿、植被重建）的恢复成效及其对区域碳平衡的影响 ...

多种复合指纹法示踪高寒区流域风水作用产沙来源

Shuitu Baochi Xuebao
目的为运用多种复合指纹法精准示踪高寒区河流、水库等水利设施在风、水复合侵蚀环境下的泥沙来源。方法在黄河龙羊峡水库支流沙沟河流域，采集风沙和水沙泥沙来源区的土壤样本，以及流域出口的新鲜泥沙样本。利用X射线荧光光谱仪测试40种元素指纹因子，采用多组指纹因子法、机器学习最佳复合指纹法、Walling⋅C最佳复合指纹法3种指纹法解析泥沙来源。结果在指纹因子筛选方面，CT-KW-DFA指纹因子筛选方法的DFA累计判别率为82.40%，CT-RF-DFA指纹因子筛选方法DFA累计判别率为100%，CT-RF ...
