土壤与所处的景观密切相关,诊断层和诊断特性是土壤系统分类中判定土壤类型的依据,诊断层和诊断特性与景观之间具有一定的联系,研究它们的关系有助于更好地辅助土壤调查。本文在景观理论的指导下,对江苏省句容市边城镇开展了样区土壤调查,调查采样的48个主要剖面归属于人为土、淋溶土、雏形土和新成土4个土纲、4个亚纲、9个土类、13个亚类;在此基础上,重点探讨了诊断层和诊断特性与景观之间的关系,结果表明景观能很好地指示某些诊断层和诊断特性,对景观的深入研究可以指导土壤调查与土壤系统分类类型的确定。
The soil is closely related to the landscape in which it is located. The diagnostic layers and diagnostic features are the basis for determining the soil type in the soil system classification. The relationship between the diagnostic layer and the diagnostic properties and the landscape has a certain relationship. Studying their relationship helps to better assist Soil survey. This paper, under the guidance of landscape theory, conducted a soil survey in the sample area of Jurong City, Jiangsu Province. The 48 main sections of the survey and sampling belonged to 4 soil classes of man-made soil, leaching soil, embryonic soil and newly formed soil, Four subclasses, nine soils and thirteen subclasses. Based on this, the relationship between the diagnostic layer and the diagnostic features and the landscape was discussed emphatically, and the results showed that the landscape can well indicate some diagnostic layers and diagnostic features In-depth study of the landscape can guide the determination of soil types and types of soil investigations.
