Soil map of Lower Saxony 1: 50 000 — Landscapes (WMS Service)

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尺度的土壤单元，仅对土壤进行宽泛的表征（例如沿海全新世（Holocene）景观、黄土与砂黄土景观等）。土壤景观以通用且多属地质类的判定准则为核心特征；其判定依据主要源自地质成因（geogenesis）与成土母质（substrates）（如以受母质制约的特定土壤类型为主，例如疏松土壤），但亦可依托水文条件（如泛滥平原与低地中占主导的地下水型土壤（groundwater soils））或地形（relief）特征（以特定地形形态为主，例如resin）进行界定。其往往还与气候条件存在关联：降雨量提升会增加土壤贮水的占比。由于土壤景观与大型地质单元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，其边界划分通常需要进行概化处理。
