【摘要】:土壤表面粗糙度是表征土壤表面微地貌的一項(xiàng)重要指標(biāo),與土壤本身水分入滲速率、地表徑流及土壤侵蝕等密切相關(guān)。土壤表面粗糙度直接影響農(nóng)作物種植、灌溉、收成等,是當(dāng)前農(nóng)業(yè)發(fā)展急需解決的關(guān)鍵問(wèn)題之一。精細(xì)平整的土地,能大幅地節(jié)約灌溉用水,提高肥料的利用率和抑制雜草的生長(zhǎng),達(dá)到低成本、高收益的目的。為此,在廣泛閱讀國(guó)內(nèi)外相關(guān)文獻(xiàn)的基礎(chǔ),主要介紹5種當(dāng)前主流的土壤表面粗糙度檢測(cè)方法及其應(yīng)用情況。通過(guò)對(duì)檢測(cè)數(shù)據(jù)獲取、檢測(cè)時(shí)間、檢測(cè)分辨率、檢測(cè)精度和土壤微地形的表征情況等指標(biāo)進(jìn)行對(duì)比,得出當(dāng)前各種土壤表面粗糙度檢測(cè)方法的研究現(xiàn)狀與存在問(wèn)題。最后總結(jié)其未來(lái)發(fā)展方向,為對(duì)該領(lǐng)域的進(jìn)一步研究提供參考依據(jù)。
[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.
