Abstract—
The study of the geochemical features of Vitric Andosols in the central part of the Tolbachik Dol Plateau near the Kleshnya and Alaid lava flows was carried out to determine the relationship between the elemental composition of parent rocks and the soils and vegetation forming on them. The elemental composition of the samples was determined by X-ray fluorescence analysis and ICP-AES. For statistical data processing, we used correlation analysis, principal component analysis, and non-metric multidimensional scaling (Statistica 7, R software). The distribution of elements in soils is largely determined by the relief conditions. The contents of Fe, Ca, and Ti throughout the study area exceed the regional background levels in the eastern part of the northern soil province of Kamchatka. Differences between plant communities growing on different lava flows are associated with the macrorelief and size of outcrops of lava debris rather than with the elemental composition of soils and underlying lava. However, there is a strong relationship between the distribution of Cu and P and the number of species and projective cover of vascular plants.

Tolbachik Dol火山高原土壤的生态和地球化学特征
摘要-
对托尔巴奇克多尔高原中部靠近 Kleshnya 和阿莱德熔岩流的 Vitric Andosol 的地球化学特征进行了研究，以确定母岩的元素组成与其上形成的土壤和植被之间的关系。样品的元素组成通过 X 射线荧光分析和 ICP-AES 确定。对于统计数据处理，我们使用相关分析、主成分分析和非度量多维标度（Statistica 7，R 软件）。土壤中元素的分布很大程度上取决于地形条件。整个研究区的 Fe、Ca 和 Ti 含量超过了堪察加北部土壤省东部的区域背景水平。在不同熔岩流上生长的植物群落之间的差异与熔岩碎片露头的宏观地形和大小有关，而不是与土壤和下伏熔岩的元素组成有关。然而，Cu和P的分布与维管植物的物种数量和投影盖度之间存在很强的关系。
