【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。
[Abstract]:Soil surface roughness is an important index to characterize the microgeomorphology of soil surface, which is closely related to the infiltration rate of soil water, surface runoff and soil erosion. The roughness of soil surface directly affects crop planting, irrigation, harvest and so on, which is one of the key problems that need to be solved in the current agricultural development. Fine and smooth land can save irrigation water greatly, improve the utilization rate of fertilizer and restrain the growth of weeds, so as to achieve the goal of low cost and high income. Therefore, on the basis of extensive reading of relevant literature at home and abroad, this paper mainly introduces five main methods of measuring soil surface roughness and their application. Based on the comparison of detection data acquisition, detection time, detection resolution, detection precision and characterization of soil microtopography, the current research status and problems of various soil surface roughness detection methods are obtained. Finally, the future development direction is summarized, which provides a reference for further research in this field.
