Soil map of Lower Saxony 1: 50 000 — Soil landscapes

Soil landscapes are supra-regional soil units that characterise the soils only very generally (e.g. because coastal holocene or the loess and sand loess landscapes). The soil landscapes are characterised by common, mostly geological criteria; these are mainly derived from geogenesis and substrates (dominance of certain substrate-dependent soil types, e.g. loose soils), but must be derived from the water conditions (predominance of groundwater soils, e.g. in floodplains and lowlands) or relief (dominance of certain relief forms, e.g. resin). Often there is also a connection to the climate (increased rainfall leads to an increased proportion of water reservoirs). Since there are close interrelationships between soil landscapes and large geological units, their boundaries can be defined according to geological maps. Due to the very small-scale representation, the demarcation is usually associated with a generalisation.土壤景观属于超区域土壤单元（supra-regional soil units），仅对土壤进行宽泛的特征描述（例如以海岸全新世、黄土与砂黄土景观为代表的类别）。土壤景观以共性特征为核心，且多数以地质判别准则为依据；这些依据主要源自地质成因（geogenesis）与成土母质（substrates）——例如以特定母质关联型土壤为主，比如松散土壤；但也可源于水文条件（如泛滥平原（floodplains）、低地中占主导的地下水型土壤（groundwater soils））或地形（relief）条件——例如以特定地貌形态为主的情况，例如resin。此外，土壤景观通常还与气候存在关联：降雨量增加会提升蓄水体的占比。鉴于土壤景观与大型地质单元之间存在紧密的相互关联，其边界可依据地质图进行划定。由于采用小比例尺制图，其边界划定通常需进行概化处理。
