Shuitu Baochi Xuebao, 2017 为研究东北地区坡耕地的春季融雪侵蚀特征及其影响因素，选取吉林省吉兴小流域内坡耕地进行原位观测，通过分析融雪过程中径流量和含沙量的变化，以及融雪径流、土壤解冻深度等指标对融雪侵蚀的影响，探讨坡耕地融雪侵蚀过程及变化规律。结果表明，在日平均温度0～3.8 ℃的气象条件下，春季融雪侵蚀较为集中，径流与含沙量变化均先增加后减少。融雪径流与表层土壤解冻深度是影响融雪侵蚀的重要因素，初期融雪产流，土壤未解冻，径流急剧增加，径流量占融雪期总径流量的59.15%；中期积雪融化趋于稳定，土壤表层开始解冻 ...

Shuitu Baochi Xuebao, 2021 为明确土壤冻融过程中水分垂直迁移与其主要影响因素间的定量关系，以我国东北典型黑土为研究对象，通过单向冻融试验，进行了不同初始含水率、降温幅度和地下水位条件下土壤冻结过程中水分垂直迁移试验，定量分析了主要影响因素对黑土冻融过程中水分垂直迁移的影响规律。结果表明：（1）试样中温度变化先快后慢，最终试样内部温度随深度呈现稳定的温度梯度分布；（2）初始含水率对土壤的冻结影响较为明显，初始含水率越高，冻结经历时间越长，冻结过程中消耗的潜热量越大，冻结锋面形成越晚；（3）不同降温幅度使得土壤温度梯度差距较大，15 ...
