黄土丘陵区不同坡度撂荒草地入渗特征影响因素试验研究

open access: yesShuitu 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~
