目的为研究不同植被恢复措施对黄土坡面降雨入渗过程的影响。方法选取黄土高原西峰南小河沟植被自然恢复(草地景观)和人工植树造林(林地景观)小流域组成配对流域。2017—2018连续采集10 min分辨率气象数据和不同坡位(山坡、沟谷)5个深度(10、20、40、60、100 cm)的土壤水分数据,探究降雨后土壤水分入渗的响应特征及影响因素。结果1)不同降雨属性显著影响土壤湿润深度和湿润速度,降雨量大、降雨强度大且历时长的降雨更容易引起土壤水分响应和水分深层下渗。2)林地促进土壤水分深层入渗。与草地(40 ...

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 ...
