Restoration of postmining areas is a frequently addressed topic requiring a comprehensive view. In this article, the recovery process of selected postmining spoil heap sites was evaluated using an approach based on calculation of Nash equilibrium (NE) probability distributions. Many of these sites have been allowed to recover by spontaneous succession, while on others, a variety of restoration procedures have been tested, most of them variants of the forest plantation type. The evaluation was carried out on selected data from each site that reflects four factors: the richness of the vegetation cover, the amount of biomass as soil macrofauna per unit area, the forestry yield, and the attractiveness for recreation use. The analysis was based on permuted game configurations in which these factors were treated as competing entities, adversaries that were differentially successful in each location depending on the conditions of the recovery procedure used. The game strategies that the factors exhibited as theoretically interacting entities had no primary information content, which meant that they could be treated stochastically. The result was a distribution of the NE probability at each location. Considering the fact that this result reflected the degree of optimality of the included factors, the calculation could be considered as a specific type of multicriteria evaluation, which was practically applicable and provided unambiguous results. The NE probability in sites restored by deciduous tree stands was higher, which was therefore assumed to correspond to higher stability.

使用博弈论方法对采矿后土地区域恢复程序的随机评估

采矿后区域的恢复是一个经常被讨论的话题，需要一个全面的观点。在本文中，使用基于纳什平衡 (NE) 概率分布计算的方法对选定的采后弃土堆场的回收过程进行了评估。许多这些地点已被允许通过自发演替恢复，而在其他地点，已经测试了各种恢复程序，其中大多数是人工林类型的变体。对来自每个地点的选定数据进行了评估，这些数据反映了四个因素：植被覆盖的丰富度、单位面积土壤大型动物的生物量、林业产量和娱乐用途的吸引力。该分析基于排列的游戏配置，其中这些因素被视为竞争实体，根据所使用的恢复程序的条件，在每个位置取得不同成功的对手。这些因素表现为理论上的相互作用实体的博弈策略没有主要的信息内容，这意味着它们可以被随机处理。结果是每个位置的 NE 概率分布。考虑到这一结果反映了所包含因素的最优程度，该计算可以被认为是一种特定类型的多准则评价，具有实际适用性并提供了明确的结果。落叶乔木恢复的地点的 NE 概率更高，因此被认为对应于更高的稳定性。
