坡长和雨强对氮素流失影响的模拟降雨试验研究

Shuitu Baochi Xuebao, 2017
为研究氮素的流失特征，探索坡长和降雨强度对氮素流失的影响，选定坡长（2，3，4，5 m）和降雨雨强（0.65，0.69，0.83，0.85，1.01，1.20，1.37，1.54，1.68，1.80 mm/min）作为可变因素，在红壤裸坡上进行室内人工模拟降雨试验。结果表明：（1）坡面径流中各形态氮素流失随时间推移基本趋势为降雨初期径流携带氮素的浓度大，随后氮素浓度下降，至20 min左右下降趋势变缓，最终径流中同一形态氮素的浓度趋于一致。（2）坡长一定时 ...

不同地表状况、降雨强度与坡度对径流水中K、Na、Ca、Mg流失量的影响

Shuitu Baochi Xuebao, 2004
采用室内模拟降雨装置,对供试的密云县农田褐土分别进行了在3种不同地表状况(裸地、草皮覆被、秸秆覆盖),3种降雨强度(60 mm/h,90 mm/h,120 mm/h),5种坡度(10°,15°,20°,25°,30°)下的交叉实验,对不同降雨时间段下表层径流水中K、Na、Ca、Mg流失量进行测试分析,结果表明在坡度10°,15°的3种降雨强度下,各阳离子流失量在相同时间段内总体表现为秸秆覆盖＜草皮覆被＜裸地,在坡度20°,25°,30°时草皮覆被对各阳离子流失量的抑制效果明显;相同地表、坡度和降雨时间段,
