The main aim of these studies was to determine the potential for carbon sequestration in brown coal open-cast mine by phytoremediation using scots pine (Pinus sylvestris L.) and giant miscanthus (Miscanthus x giganteus) plants. This paper presents relationships between soil organic carbon (SOC) sequestration and carbon phytosequestration in waste dump associated with open-cast lignite mine in Central Poland. The research is the continuation of previously carried out experiments, but was conducted in field conditions. In reclamation of post-mining landscapes, during field experiment, an effect of sewage sludge, compost and lake chalk amendments and in combination of plants was investigated. The impact of soil amendments on carbon stock, CO emission reduction, plant biomass production and carbon content in shoots and roots was studied. The highest SOC stock was found in soil treated with sewage sludge (33 Mgha) and compost (45 Mgha) stabilized by lake chalk. These fertilizer combinations also contributed the most in relation to CO emission reduction through SOC stock (83 Mgha and 127 Mgha respectively). In addition, greater amounts (60-100%) of soil organic matter was converted into humic acids fraction. This phenomenon could be the initial stage of the progressive process of organic matter deposition and carbon sequestration in post-mining area. Carbon phytosequestration was determined through carbon bound in plant tissues. The highest carbon content (60%) in both plant species was recorded in treatments with sewage sludge and compost with lake chalk. Stabilization of compost by lake chalk application was good method to improve the efficiency of carbon sequestration in soil and carbon phytosequestration. Improving the efficiency of these two processes, through skillfully selected soil additives and plant species, may be used on a larger scale in the future as an alternative to the storage of carbon dioxide, especially in degraded areas.
这些研究的主要目的是通过利用欧洲赤松（Pinus sylvestris L.）和巨型芒草（Miscanthus x giganteus）植物的植物修复来确定褐煤露天矿通过植物固定碳的潜力。本文介绍了波兰中部褐煤露天矿排土场与土壤有机碳（SOC）固存和碳植物固定之间的关系。该研究是以前进行的实验的延续，但在野外条件下进行。在露天矿后景观的复垦过程中，在田间试验中，研究了污水污泥、堆肥和湖白垩改良剂以及植物组合的影响。研究了土壤改良剂对碳储量、CO 减排、植物生物量生产和地上部和根中碳含量的影响。在经过湖白垩稳定的污水污泥（33 Mgha）和堆肥（45 Mgha）处理的土壤中发现 SOC 储量最高。这些肥料组合在通过 SOC 储量减少 CO 排放方面的贡献也最大（分别为 83 Mgha 和 127 Mgha）。此外，更多的土壤有机质（60-100%）转化为腐殖酸。这种现象可能是有机质在矿区逐渐沉积和碳固定的初始阶段。植物组织中结合的碳确定了碳的植物固定量。在添加了污水污泥和堆肥与湖白垩的两种植物中，碳含量最高（60%）。湖白垩在堆肥中的应用稳定化是提高土壤固碳和碳植物固定效率的好方法。通过巧妙选择土壤添加剂和植物物种，提高这两个过程的效率，将来可能会在更大的范围内作为二氧化碳储存的替代方法，尤其是在退化地区。
