摘要

摘要所研究的飞灰沉积物的模型回收过程始于2003年,形成了五个不同的实验表层,其中含有不同组合的飞灰和有机物。然后,在这些表层上播种草料混合物。2015年,对在开垦过程中应用的不同表层变体上生长的植物群落的选定特性进行了评估。据推测,该过程中使用的矿物和有机基质的类型及其质量是影响修复表面不同变体上长期植物多样性的主要因素。该分析的目的是评估灰烬废物回收(在五种不同类型的表层上进行)自启动以来12年的有效性。回收过程的长期结果表明,由于实验表面的所有变体都被茂密的植被完全覆盖,因此所施加的表层可以有效回收灰烬。来自原始和分段栖息地的植物物种占优势,表明实验栖息地的土壤肥沃,pH值为中性和微碱性,质地为沙壤土。具有有利碳氮比、中性或微碱性的沙子质地的实验表层并没有限制植物的发育。有机废弃物的利用显著促进了自发发展的植被的区系多样性。在一些实验变体中使用的针叶树皮对其区系的独特性有显著影响,因为存在偏好较低pH值栖息地的物种。

Impact of Different Reclamation Modes of Fly Ash Deposits on Species Richness of Spontaneous Flora
ABSTRACT The model reclamation process of the studied fly ash deposits has been started in 2003 by formation of five different experimental surface layers containing fly ash and organic matter in various combinations. Then, grass mixture was sown on these surface layers. In 2015, selected properties of plant communities growing on different variants of surface layers applied in the reclamation process were assessed. It was assumed that the type of mineral and organic substrates used in the process and their quality were the main factors affecting the long term plant diversity present on different variants of restored surfaces. The aim of this analysis was the assessment of the effectiveness of ash waste reclamation (carried out on five different types of the surface layer) after 12 years since its initiation. The long term results of the reclamation process showed that the applied surface layers allowed for an effective reclamation of ashes since all variants of experimental surfaces were totally covered by dense vegetation. The predominance of plant species from ruderal and segetal habitats indicated that the soil of the experimental habitats was fertile with neutral and slightly alkaline pH, and texture of sandy loams. The experimental surface layers with a texture of sand of favourable C:N ratio, neutral or slightly alkaline did not limit the plant development. The use of organic waste markedly contributed to the floristic diversity of the spontaneously developed vegetation. Coniferous bark used in some experimental variants had a marked effect on their floristic distinctiveness due to the presence of species preferring habitats of lower pH values.
