The total area of abandoned milled peatlands which need to be rehabilitated for sustainable land-use is nearly 10,000 ha in Estonia. According to the agreement between Estonia and the European Union, Estonia has to create suitable conditions for restoration of 2000 ha of abandoned cut-away peatlands by 2023. The decisions on rehabilitation of abandoned milled peatlands have so far relied on a limited knowledgebase with unestablished methodologies, thus the decision making process needs a significant improvement. This study aims to improve the methodology by identifying the criteria for optimal decision making to ensure sustainable land use planning after peat extraction. Therefore relevant environmental, social and economic restrictive and weighted comparison criteria, which assess reuse alternatives suitability for achieving the goal, is developed in cooperation with stakeholders. Restrictive criteria are arranged into a decision tree to help to determine the implementable reuse alternatives in various situations. Weighted comparison criteria are developed in cooperation with stakeholders to rank the reuse alternatives. The comparison criteria are organised hierarchically into a value tree. In the situation, where the selection of a suitable rehabilitation alternative for a specific milled peatland is going to be made, the weighted comparison criteria values need to be identified and the presented approach supports the optimal and transparent decision making. In addition to Estonian context the general results of the study could also be applied to a cut-away peatlands in other regions with need-based site-dependent modifications of criteria values and weights.
在爱沙尼亚，需要进行修复以实现可持续土地利用的废弃泥炭地总面积近10000公顷。根据爱沙尼亚与欧盟的协议，爱沙尼亚必须在2023年前为2000公顷废弃采掘泥炭地的恢复创造适宜条件。到目前为止，关于废弃采掘泥炭地修复的决策依赖于有限的知识库和未确立的方法，因此决策过程需要大幅改进。本研究旨在通过确定最佳决策标准来改进方法，以确保泥炭开采后的可持续土地利用规划。因此，与利益相关者合作制定了相关的环境、社会和经济限制及加权比较标准，这些标准评估再利用替代方案实现目标的适宜性。将限制标准排列成决策树，以帮助确定在各种情况下可实施的再利用替代方案。与利益相关者合作制定加权比较标准，对再利用替代方案进行排名。比较标准按层次结构组织成价值树。在为特定采掘泥炭地选择合适的修复替代方案的情况下，需要确定加权比较标准值，所提出的方法支持最佳和透明的决策。除了爱沙尼亚的情况外，该研究的总体结果也可应用于其他地区的采掘泥炭地，但需根据具体情况对标准值和权重进行基于需求的调整。
