| 摘 要： | 选择宁夏南部半干旱黄土丘陵区的彭阳县中庄小流域，针对其多年来水保措施的治理成效，利用小型人工模拟降雨和双环注水法入渗试验装置技术，对全流域不同生态恢复与重建地（水平沟、鱼鳞坑、水平梯田、人工牧草、天然草地），不同地形地貌（坡向、坡位、坡度）进行了多点土壤入渗速率实测。试验结果表明，该流域土壤入渗速率具有明显的坡面垂直变异规律，随着坡度的增加，土壤稳渗率增加，阴坡土壤稳渗率高于阳坡，但其初渗率小于阳坡；坡位对稳渗率的影响表现为南坡上到坡下稳渗率逐渐提高。土地利用方式不同，入渗速率也存在较大差异。

| Abstract: | In the semiarid loess hilly and gully area of Southern Ningxia Hui Autonomous Region,the small watershed of Zhongzhuang in Pengyang County was chosen in view of the management effects of soil and water conservation.By using a light rainfall simulator and double-ring infiltrometers,infiltration rate was measured in the spots with different ecological restoration and reconstruction measures(level trench,scale pit,level terraced field,artificial forage grass,and natural pasture) and different landforms(slope a... |
