坡面氮素流失的坡度和雨强效应模拟研究

Shuitu Baochi Xuebao, 2018
为了研究坡面径流和壤中流中全氮（TN）的流失特征，探索坡度和雨强对TN流失的影响，以风化花岗岩母质发育的土壤为研究对象，选定坡度（5°，8°，15°，25°）和降雨强度（60，90，120，150 mm/h）作为可变量，采用原状土搬迁的方式，在室内设计的径流槽上进行人工模拟降雨试验，设计试验降雨时长为坡面径流产流后90 min，壤中流水样收集延续直至无出流为止。结果表明：（1）坡面径流TN流失浓度在产流初期快速下降，随雨强的减小或坡度的增大而增大，产流后期浓度趋于稳定且差距不大。（2 ...

太行山土石山区侵蚀性降雨对典型植物措施产流产沙的影响

Shuitu Baochi Xuebao, 2017
通过对山西省长治市白马小流域的1个标准小区和4个植物措施小区近5 a（2006—2010年）的降雨和径流泥沙观测，研究太行山土石山区的降雨特征以及不同类型降雨对典型植物措施小区径流泥沙的影响。结果表明：（1）太行山土石山区侵蚀性降雨主要集中于5—8月份，7—8月份侵蚀性降雨次数占侵蚀性降雨总次数的54.55%，侵蚀性降雨量占侵蚀性降雨总量的61.19%，故该时期是防治水土流失的关键时期；（2）径流量R与降雨量P、最大30 min降雨强度I30、降雨量和最大30 min降雨强度的乘积PI30呈正相关且在0.
