几个世纪以来，土地管理历史可以影响土壤有机碳（SOC）储量。本研究评价了中世纪垄沟耕地管理对森林有机碳的影响。在矩形田中，连续顺时针耕作使表土从条形田的外部向中心移动，从而形成外围有沟、中心有脊的波纹状微地形。这种耕作技术使以前的表土埋在垄下。研究了人为微地形和百年表土埋藏对森林有机碳空间分布和储量的影响。在德国不同质地的土壤上，对落叶林中5个有垄沟田带的地点进行了采样，并对田带进行了3个正交的样条，确定了一个既没有净土壤清除也没有净土壤积累的参考位置。重新造林发生在17世纪到19世纪之间。在0 ~ 10 cm深度，平均有机碳含量为28±3g kg - 1at山脊，37±3g kg - 1at参考位置和47±5 g kg - 1at犁沟。土壤有机碳储量在垄沟处比参考位置低7±5%，在垄沟处比参考位置高8±4%。谷沟通过凋落叶积累增加了谷沟的碳输入，表现为谷沟的游离光组分有机碳含量（10±5 g kg−1）高于垄沟（6±3 g kg−1），谷沟的特定有机碳矿化（37±4 μg CO2-C g−1SOC）高于垄沟（31±3 μg CO2-C g−1SOC），谷沟的碳氮比（18±1）高于垄沟（17±1）。垄下掩埋表层土（深度20 ~ 33 ~ 52 cm）的有机碳含量不显著低于沟下和参比位置对应样品。然而，土壤有机碳含量在山脊处比参考位置高0.4 ~ 0.9 g kg - 1，这表明在山脊下埋藏长期保存了前表层土壤有机碳，尽管碳埋藏导致的土壤有机碳储量增加并不能在所有地点得到显著证实。结果表明，中世纪垄沟耕作遗留下来的微地形和古表土埋藏仍然影响着森林有机碳的空间分布和储量。
Land management history can influence soil organic carbon (SOC) stocks over centuries. In this study, the impact of medieval ridge and furrow cropland management on SOC in forests was assessed. Continuous clockwise ploughing in rectangular fields moved topsoil from the outer part of strip-shaped fields towards the centre, thus forming a corrugated microtopography with peripheral furrows and central ridges. This tillage technique led to the burial of former topsoil under the ridges.The effect of this human-created microtopography and the centuries old topsoil burial on forest SOC spatial distribution and stocks was investigated. Five sites with ridge and furrow field strips under deciduous forests on soils of differing texture in Germany were sampled, with three orthogonal transects of the field strips and a defined reference position where neither net soil removal nor accumulation occurred. Reforestation took place between the 17th and 19th century.At 0 to 10 cm depth, average SOC content was 28 ± 3 g kg− 1at ridges, 37 ± 3 g kg− 1at reference positions and 47 ± 5 g kg− 1at furrows. SOC stocks were 7 ± 5% lower at ridges and 8 ± 4% higher at furrows than at reference positions. Enhanced C input at furrows through leaf litter accumulation was indicated by higher SOC content in the free light fraction at furrows (10 ± 5 g kg− 1) than at ridges (6 ± 3 g kg− 1), higher specific SOC mineralisation (37 ± 4 μg CO2-C g− 1SOC at furrows and 31 ± 3 μg CO2-C g− 1SOC at ridges) and wider C/N ratio at furrows (18 ± 1) compared with ridges (17 ± 1).Buried topsoil under ridges (20 to 33–52 cm depth) did not contain significantly less SOC than corresponding samples at furrows and reference positions. However, SOC content was 0.4 to 0.9 g kg− 1higher at ridges than at reference positions, indicating long-term preservation of former topsoil SOC by burial under ridges, although enhanced SOC stocks at ridges due to carbon burial could not be significantly confirmed for all sites. It can be concluded that preserved microtopography over centuries and ancient topsoil burial, a legacy of medieval ridge and furrow cultivation, still influences forest SOC spatial distribution and stocks.
