Soils as balancing bodies in water balance 2071-2100 to 1971-2000 “No climate protection” scenario (RCP8.5)

The map shows the change of soils as balancing bodies in the water balance 2071-2100 compared to 1971-2000 under the “No-Climate” scenario (RCP8.5). Basically, all unsealed floors are a balancing body in the water balance (AKWH). They absorb water and release it time-delayed. In addition, water is passed through it into deeper layers. The soils thus act as a temporary storage in the landscape water balance. The method summarises all the components, e.g. water conductivity and water storage capability, into an assessment scheme to assess the retention of water in the soil. Central is the assessment of retention performance and infiltration performance. The climate models are driven by the “No-Climate Protection” scenario (RCP8.5). This is a scenario of the IPCC, which describes a continuous increase in global greenhouse gas emissions, resulting in an additional radiative propulsion of 8.5 watts per m² compared to pre-industrial levels by the end of the 21st century. The results of all climate models are equally likely. Therefore, in addition to the mean, which shows a tendency, the upper (maximum) and lower (minimum) edge of the result bandwidth can be retrieved via the maptip.本地图展示了在"无气候"情景（No-Climate，RCP8.5）下，2071-2100年与1971-2000年基准期相比，土壤作为水平衡调节体的变化情况。 本质上，所有未硬化地面均为水平衡调节体（AKWH），它们可吸收水分并延时释放，同时还会将水分向下输送至深层土层。因此，土壤在景观水平衡体系中充当临时储水单元。该方法将水分传导率、储水能力等所有相关要素整合为一套评估体系，用于评价土壤的持水性能，其核心为持水性能与入渗性能的评估。 本研究所用的气候模式由"无气候防护"情景（No-Climate Protection，RCP8.5）驱动。该情景由政府间气候变化专门委员会（IPCC）提出，描述了全球温室气体排放持续增长的态势，至21世纪末，全球辐射强迫较工业化前水平额外增加8.5瓦/平方米。 所有气候模式的模拟结果可信度均等。因此，除了能够体现变化趋势的平均值之外，还可通过地图提示框（maptip）获取结果区间的上限（最大值）与下限（最小值）边界。
