Effect of initial soil moisture content on nitrate transportation in loessial soil under artificially simulated rainfall conditions

open access: yes, 2008
利用室内人工模拟降雨,研究了不同初始含水量砂黄土在降雨条件下入渗-径流、土壤侵蚀,以及NO3--N随径流流失和土壤深层淋溶特征。结果表明,初始含水量对产流时刻的影响在相对含水量为49.4%和76.9%之间存在一个转折点,高初始含水量较低含水量产流提前大约15 min;土壤侵蚀量随着土壤初始含水量的增加而增加,相对含水量为97.1%时,侵蚀泥沙量分别是相对含水量22.9%时的2.8倍,49.4%时的2.3倍,76.9%时的1.5倍。初始含水量高的处理径流初始NO3--N浓度高,随后各处理均衰减很快,10 ...
