Abstract
灌溉地土壤侵蚀问题已经越来越引起人们的普通关注。该文采用微型水槽的室内模拟试验 ,对利用 PAM及波涌灌溉等技术减少沟灌引起的土壤侵蚀效果进行了试验研究 ,分析了在不同坡度、不同流量条件下 PAM及灌溉间歇时间对侵蚀的影响。结果表明 :PAM可显著减少沟灌土壤侵蚀量 ,地面坡度是地面灌溉土壤侵蚀最主要影响因素 ,而流量及波涌灌间歇时间对它的影响较小灌溉地土壤侵蚀问题已经越来越引起人们的普通关注。该文采用微型水槽的室内模拟试验 ,对利用 PAM及波涌灌溉等技术减少沟灌引起的土壤侵蚀效果进行了试验研究 ,分析了在不同坡度、不同流量条件下 PAM及灌溉间歇时间对侵蚀的影响。结果表明 :PAM可显著减少沟灌土壤侵蚀量 ,地面坡度是地面灌溉土壤侵蚀最主要影响因素 ,而流量及波涌灌间歇时间对它的影响较
