Shuitu Baochi Xuebao, 2019 降雨特征和坡度是影响土壤入渗过程的重要因素，在植被恢复过程中，其对土壤入渗特征的影响可能会有所不同。选取黄土丘陵区6个坡度（5°，10°，15°，20°，25°和30°）的撂荒草地（2年）径流小区（5 m×20 m），观测自然降雨条件下（共计34场降雨，产流11场）植被生长旺期（7-9月）土壤入渗特征，研究降雨过程参数（降雨量、平均雨强、降雨历时和I30）、坡度和植被盖度对坡面入渗特征的影响。结果表明：（1）11场产流降雨不同坡度土壤入渗量总体变化范围为6.58~70.91 mm，入渗补给系数为0.83~

Shuitu Baochi Xuebao, 2021 为探索喀斯特地下浅层裂隙土壤水分运移规律，通过野外调查、单环入渗试验探索裂隙土壤的入渗特性及入渗模型的适应性。结果表明：（1）裂隙土壤初始入渗率为21.06~57.90 mm/min，入渗时间20~60 min后达到稳定入渗（4.21~13.69 mm/min），且入渗初期到最后的稳渗阶段存在着较大降幅（40.89%~89.08%），与非喀斯特地区相比，喀斯特裂隙土壤的入渗速率更快；裂隙土壤各入渗特征处于中等程度变异（变异系数为0.52~0.67）。（2）裂隙土壤各入渗特征与各土壤属性显著性相关较少 ...
