毛乌素沙地不同林龄樟子松水源涵养功能

Shuitu Baochi Xuebao
目的为明确不同林龄樟子松水源涵养功能的差异。方法基于2023—2024年野外定位观测试验获得的穿透雨量、树干径流量、土壤体积含水率和枯落物质量含水率，量化不同林龄（10、15、20 a）樟子松的水源涵养功能差异。结果随着林龄增长，冠层结构发育显著改变降水分配格局，穿透雨和树干径流占比相对降雨量降低，而冠层截留能力持续增强，反映成熟冠层对降雨再分配的关键作用，10、15、20 a林龄冠层截留量分别占降雨量17.7%、29.4%和35.4%。林下枯落物层的发育呈显著年龄效应 ...

洱海流域水源涵养与土壤保持功能时空演变及权衡协同关系

Shuitu Baochi Xuebao
目的为厘清2000—2020年洱海流域水源涵养与土壤保持服务的时空演变规律、空间耦合关系及其背后的驱动机制，提升高原湖泊流域的生态管理水平。方法基于InVEST与CSLE模型，定量评估洱海流域2000—2020年水源涵养与土壤保持服务的时空演变格局，并结合地理探测器方法识别主控因子，通过协同-权衡识别方法与空间自相关分析，探讨二者耦合关系及其空间异质性。结果1）2000—2010年洱海流域产水量下降42.19%，2020年虽有所回升，但整体水源涵养功能较2000年下降21.3%；土壤保持量则持续上升 ...
