| 1 | 降雨过程中碱性坡耕地土壤侵蚀的研究显示文摘坡地土壤侵蚀的治理是水土保持工作的主要任务之一。为了研究碱性坡耕地土壤在降雨过程中的入渗和侵蚀特性 ,该试验采用室内人工降雨模拟器方法对两种不同碱度的壤质黄土在不同坡度条件下的入渗和侵蚀进行了调查。试验土壤的可交换钠百分比 (ESP) 分别为 2 .8和 5 2 .0 ,土壤表面坡度为 5 %~ 2 5 %。试验数据显示 ,在降雨过程中 ,土壤的入渗能力随 ESP的减小或表面坡度的增大而增加 ,土壤的可侵蚀性随土壤 ESP或表面坡度的增大而增加。两种 ESP的土壤在各种表面坡度情况下的土壤累积侵蚀量随累积降雨量直线增加 ,并随土壤坡度的增大而增加。但当土壤坡度大于 15 %时 ,高ESP土壤的累积侵蚀量随土壤坡度的增加远大于低 ESP土壤的增加。U SL E经验公式较好地预测了低 ESP土壤的坡度系数 ,但不能精确计算高 ESP土壤的坡度系数。由于土壤细沟侵蚀的发生 ,WEPP模型低估了两种 ESP土壤在大坡度情况下的坡度系数。 | 李法虎 Keren R Benhur M | 2003 | 农业工程学报2003，19，2： | 8 |
