Application papers — Organic carbon stored in the soils of the Apennines between 0-100 cm

The paper of organic carbon stored in the soils of the Emilia-Romagna Apennines, is understood as the first processing through polygons that describe the average content of organic carbon expressed in Mg*ha-1 in the first 100 cm of soil plus the content of the organic surface horizons in the case of forest soils. It provides a spatial data. The CO content in the first 100 cm of soil and organic horizons in forest soils considers the distribution of different types of soil and the incidence of non-soil areas, understood as areas occupied by surface water, urban and infrastructure. The representation of the territory takes place through a knitted structure consisting of cells with 1Km side. The value attributed takes into account the zero contribution due to non-soil areas. The attribution of the value to the cell takes into account the distribution of soils according to the Land Charter of the Emilia-Romagna Region (scale 1:250,000, ed. 1994 and updated.); the distinction between land-occupied and non-soil-occupied areas (i.e. urban, infrastructure or surface water) derives from the Land Use Charter 2003 on a scale of 1:25,000 drawn up by the Geographic Information Systems Service of the Emilia-Romagna Region.本数据集围绕艾米利亚-罗马涅亚平宁山区的土壤有机碳储量展开，其核心为首次通过多边形单元完成的处理流程：该多边形单元用于描述0~100cm土层的有机碳平均含量（单位为Mg·ha⁻¹），若为森林土壤则额外计入有机表层的有机碳储量。本数据集提供空间数据。针对0~100cm土层及森林土壤有机表层的有机碳含量，计算过程兼顾了不同土壤类型的分布特征，并纳入了非土壤区域的影响——非土壤区域指被地表水、城市及基础设施占用的区域。研究采用由边长1千米的格网单元构成的格网结构表征研究区域，格网赋值时将非土壤区域的有机碳贡献计为0。格网单元的数值赋值依据艾米利亚-罗马涅大区《土地宪章》（Land Charter of the Emilia-Romagna Region，比例尺1:250000，1994年版且已更新）中的土壤分布信息完成；而土地占用区域与非土壤区域（即城市、基础设施或地表水区域）的区分，则基于艾米利亚-罗马涅大区地理信息系统服务团队编制的2003年版《土地利用宪章》（比例尺1:25000）实现。
