| 摘 要： | 合理利用微咸水资源是解决水资源危机的一条重要途径。微咸水灌溉对土壤侵蚀的研究较少。本文采用微型土槽室内模拟试验,对微咸水沟灌引起的土壤侵蚀效果进行了试验研究,分析了在固定流量下不同坡度和不同水质条件对土壤侵蚀的影响,以期为改善和提高微咸水地面灌溉地区水土资源的管理水平提供理论依据。试验结果表明:相同坡度及相同流量处理下,土壤侵蚀量随灌溉水钠吸附比的增大而增加,随电导率的增大而减小;地面坡度是沟灌土壤侵蚀的主要因素,随坡度的增加土壤侵蚀量也不断增加。 |
| 关 键 词： | 微咸水沟灌 土壤侵蚀 电导率 钠吸附比 微型土槽 |

| Abstract: | Using brackish water resource reasonably is an important approach to solve water resource crisis.The present research on brackish water irrigation in our country pays less attention to soil erosion induced by brackish water irrigation activity.Simulated laboratory experiments with mini-flume are conducted to study soil erosion induced by the furrow irrigation with brackish water.From the mini-flume experimental data,the impacts of different water quality and slopes under certain inflow rate are quantitative... |
| Keywords: | furrow-irrigation with brackish water soil erosion electrical conductivity sodium adsorption ratio mini-flume |
