摘要

目的。研究的目的是研究Chervonohrad矿区Nadiya矿山岩石场化学污染的特殊性,根据地形条件和边坡暴露程度,分析化学元素在自然背景下分布的总体趋势。方法。在弥散分析的基础上,研究了纳迪亚矿山岩石场在生态环境水平上的化学污染分异;生态环境在地球化学指标空间上的多维排序——基于主成分分析基于判别分析,构建了矿山排土场生态环境类型方案;化学污染参数的统计处理。发现。已经确定,即使在相同的边坡暴露范围内,Nadiya矿山岩石堆的化学污染水平也具有显著的非均质性。化学元素在分布上的相似性使得可以区分它们的6种组合,其中主要是I (Mg, Ca, S)和II (Al, Fe, K, Si)。对化学元素浓度之间的依赖性的分析表明,许多参数之间存在着密切的联系。研究表明,Mg、Pb、Sn、Fe、Al、Cu、P、Ni、Zn等元素与人为负荷强度的关系最为密切。不同排土场暴露的生态环境差异主要是由Ca和Al浓度水平引起的。创意。首次揭示了Chervonohrad矿区Nadiya矿山岩石场具有一个生态空间的特征,并以复杂的环境地球化学梯度为轴对生态空间进行了排序。矿山矸石堆的类型方案反映了与自然背景相比土壤覆盖化学污染的梯度。实际意义。通过确定某一时期生态区的地球化学条件,可以确定其在排土场植被生态-生态空间中的位置,并预测各种形式的人为影响下植被覆盖的稳定性和可能发生的变化。

Chemical pollution peculiarities of the Nadiya mine rock dumps in the Chervonohrad Mining District, Ukraine
Purpose. The research purpose is to study the peculiarities of chemical pollution of the Nadiya mine rock dumps in the Chervonohrad Mining District, depending on the relief conditions and slope exposure, as well as to analyze the general trends in the distribution of chemical elements compared to the natural background. Methods. The chemical pollution differentiation of the Nadiya mine rock dumps at the level of ecotopes is studied on the basis of dispersion analysis; multidimensional ordination of ecotopes in the space of geochemical indicators – based on the Principle Component Analysis; a typological scheme of mine rock dump ecotopes is constructed based on discriminant analysis; statistical processing of chemical pollution parameters. Findings. It has been determined that the level of chemical pollution of the Nadiya mine rock dumps is characterized by significant heterogeneity even within the same slope exposure. Similarity in the distribution of chemical elements makes it possible to distinguish 6 of their associations, the main of which are I (Mg, Ca, S) and II (Al, Fe, K, Si). An analysis of the dependence between the chemical element concentrations indicates a close link between many parameters. It has been revealed that the closest dependence on the anthropogenic load intensity is demonstrated by such elements as Mg, Pb, Sn, Fe, Al, Cu, P, Ni, Zn. It has been determined that the difference between the ecotopes of different dump exposures is explained mainly by the level of Ca and Al concentration. Originality. It has been revealed for the first time that the Nadiya mine rock dumps of the Chervonohrad Mining District are characterized by an ecological space, which is assessed on the basis of the ordination of ecotopes on the axes of complex geochemical gradients of the environment. The typological scheme of mine rock dumps reflects the gradient of soil cover chemical pollution compared to the natural background. Practical implications. By determining the geochemical conditions of ecotopes in a certain period of time, it is possible to identify their position in the ecological-cenotic space of dump vegetation, as well as to predict the stability and possible changes in the vegetation cover as a result of various forms of anthropogenic impact.
