摘　　要：土壤表面粗糙度是表征土壤表面微地貌的一项重要指标,与土壤本身水分入渗速率、地表径流及土壤侵蚀等密切相关。土壤表面粗糙度直接影响农作物种植、灌溉、收成等,是当前农业发展急需解决的关键问题之一。精细平整的土地,能大幅地节约灌溉用水,提高肥料的利用率和抑制杂草的生长,达到低成本、高收益的目的。为此,在广泛阅读国内外相关文献的基础,主要介绍5种当前主流的土壤表面粗糙度检测方法及其应用情况。通过对检测数据获取、检测时间、检测分辨率、检测精度和土壤微地形的表征情况等指标进行对比,得出当前各种土壤表面粗糙度检测方法的研究现状与存在问题。最后总结其未来发展方向,为对该领域的进一步研究提供参考依据。Soil surface roughness is a important indicator to descript soil surface micro- topography,which affects infiltration rate,runoff and soil erosion. Soil surface roughness has a direct impact crop planting,irrigation,harvest,and is one of the key issues need to be resolved in the current agricultural development. Fine and level paddy field can significantly help save irrigation water,raise fertilizer utilization,and suppress weeds so as to get good harvest with low cost.Soil surface roughness measurement is the first task we need to solve. This research begin with far and wide reading at home and abroad related literatures,then introduce five main different soil surface roughness measurement- methods with its application currently. Through compare with the detection of data acquisition,resolution,precision andsiol micro- topography characterizes,we find out the current status and insufficient between different methods. In the end,we summarize its trend in development,and give the basis for further study in this area.
