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 ...

基于多源地理数据的西南高山峡谷区生态系统服务评估及权衡与协同关系

Shuitu Baochi Xuebao
[目的] 西南高山峡谷区是国家"三区四带"重要生态安全屏障,对保障国家生态安全和区域高质量发展具有重要作用,但目前尚不明确该区生态系统服务及其权衡与协同关系。[方法] 基于InVEST模型、RUSLE模型和WR指数,结合多源地理数据集,系统评估了西南高山峡谷区2000—2020年3种典型生态系统服务,并揭示其权衡与协同关系。[结果] (1)2000—2020年,西南高山峡谷区固碳和水源涵养服务稳步提升,年均固碳服务由1 927 g/(m2·a)增加到1 985 g/(m2·a),WR指数从0 ...
