Test backdrop III - locations with climate protection potential to be tested (LBK 1984-2004)

Test set III is one of three test sets in which (in ascending order) the presence of peatland biotope types and the soil properties of a peat cover relevant to climate protection, i.e. a theoretical greenhouse gas reduction potential in rewetting, should be checked. In accordance with the LBEG, the areas of national biotope mapping (1984-2004) identified here are classified as carbon-rich soils with significance for climate protection (BHK50). Due to their biotope type, however, the areas of the National Biotope Mapping (1984-2004) shown here indicate either mineral sites or heavily over-embossed biotopes due to their anthropogenic nature. As with Test Scenario II, it should also be examined here whether the soils are already too degraded for rewetting with greenhouse gas mitigation potential to be realistic. In addition to possible anthropogenic impairments of the bog body, the deviations between soil and biotope data in Test Scene III can also be due to uncertainties in the data basis, such as inaccuracies in the soil map or, if necessary, incorrect biotope type mapping. Since there is a possible discrepancy between soil and biotope type data, these areas should be checked for their site characteristics.The backdrop is based on the results of the survey of areas of value for nature conservation in Lower Saxony (National Biotope Mapping, 2. passage, from 1984 to 2004). The areas shown are areas of national importance for the protection of species and ecosystems as well as the protection of earth-historical landscape forms, which were worthy of protection at the time of the mapping from the point of view of the specialist authority for nature conservation.测试集III为三个测试集之一，按升序排列的前提下，需在此验证泥炭地生境类型（peatland biotope types）的存在情况，以及与气候保护相关的泥炭覆盖层土壤特性——即湿地复水措施下的理论温室气体减排潜力。根据LBEG的相关规定，此处标注的1984-2004年国家生境制图（national biotope mapping）区域，被归类为具有气候保护价值的富碳土壤（carbon-rich soils），即BHK50。然而，基于其生境类型，此处展示的1984-2004年国家生境制图覆盖区域，要么属于矿质地段（mineral sites），要么属于因人为活动导致的重度改造生境。与测试场景II（Test Scenario II）一致，本次任务同样需验证：土壤是否已发生过度退化，以至于通过复水实现温室气体减排潜力的目标不具备现实可行性。除泥炭体（bog body）可能遭受的人为破坏外，测试集III中土壤与生境数据之间的偏差，也可能源于数据基础的不确定性——例如土壤图（soil map）存在精度偏差，或必要时生境类型制图（biotope type mapping）出现错误。鉴于土壤与生境类型数据间可能存在不一致，需对这些区域的位点特性开展核查。本数据集的背景基于德国下萨克森州（Lower Saxony）1984-2004年自然保护价值区域调查成果（即国家生境制图第二部分）。此处展示的区域，是当时德国下萨克森州自然保护主管部门基于专业视角认定的、具有全国重要性的物种与生态系统保护，以及地球历史景观形态保护区域。
