Abstract

This paper discusses the composition of soil–water extracts prepared from soils developing within a heterolithic geochemical landscape of the Klyazma River basin at the upper reaches of the river. The main factors determining the content of water-soluble components are the soil genesis and position in the series of elementary landscapes. The content of water-soluble macro- and microelements in soil profiles not affected by anthropogenic impacts is determined by the eluvial–illuvial structure of these soils. In a superaqual landscape withdrawn from the floodplain regime and featuring a complex soil cover, the distribution of water-soluble components in the soil profile is determined by calcareousness of soil–ground waters and their occurrence depth. Another factor affecting the soil solution composition is peat deposits underlying the soils. It is shown that calcium is one of the key elements determining the specificity of the studied heterolithic landscape. The performed cluster analysis confirms the identified differences in the composition of water-soluble components in each of the studied soils.

南针叶林次区域杂岩结合景观土壤中的水溶性成分

摘要

本文讨论了从上游的Klyazma河盆地的异质地球化学景观中发育的土壤中制备的土壤-水提取物的组成。决定水溶性成分含量的主要因素是土壤的成因和一系列基本景观中的位置。土壤剖面中水溶性宏观元素和微量元素的含量不受人为因素的影响，取决于这些土壤的冲积构造。在从洪泛区撤出的超等景观中，土壤覆盖物复杂，土壤剖面中水溶性成分的分布取决于土壤-地下水的钙质及其发生深度。影响土壤溶液成分的另一个因素是土壤下面的泥炭沉积物。结果表明，钙是决定所研究的异质岩景观特异性的关键因素之一。进行的聚类分析证实了每种研究土壤中水溶性成分组成的差异。
