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。

Soils have close connection with landscapes, diagnostic horizons and characteristics are the base for determining soil types in soil taxonomy. It is helpful for soil survey to study the relationship between landscapes and diagnostic horizons and characteristics. In this paper, under the guidance of the landscape, we carried out the survey of soil series in a small scale area in Jurong county of Jiangsu Province, 48 main profiles were classified into 4 soil orders (Anthrosols, Luvisols, Cambisols and Entisols), 4 suborders, 9 groups, 13 subgroups. Based on the survey, we explored diagnostic horizons and characteristics relationship with landscapes, and found that landscape can well indicate some diagnostic horizons and characteristics, the in-depth study of landscape can guide soil investigation and determine soil types.
