The paper addresses the removal of chemical elements by suprasoil and subsoil phytomasses of herbaceous phytocenoses and their subsequent return to soil during decomposition of plant remnants. The obtained results allowed us to evaluate the biogeochemical cycles of essential (Zn, Cu) and toxic (Pb, Cd) elements in natural biogeocenoses of the Middle Urals. It has been shown that the intensity of such an exchange in areas subjected to variable anthropogenic impact is determined not only by the direct influence of mobile forms of chemical elements, which are contained in soils and operate as environmental pollutants, but also by a combination of edaphic (physicochemical parameters of soils), coenotic (abundance and correlation of agrobotanical groups in phytocenosis) and microbiological (level of evolution of soil microbiocenosis) conditions.

影响区域的生物地球化学：土壤和植物群落环境因素的作用

该论文讨论了草本植物群的上层土壤和下层土壤植物群对化学元素的去除，以及它们在植物残余物分解过程中随后返回土壤的问题。获得的结果使我们能够评估中乌拉尔自然生物地球中心的必需（Zn、Cu）和有毒（Pb、Cd）元素的生物地球化学循环。已经表明，在受到不同人为影响的地区，这种交换的强度不仅取决于土壤中含有并作为环境污染物运行的化学元素的可移动形式的直接影响，而且还取决于以下因素的组合：土壤（土壤的物理化学参数）、共生（植物群落中农用植物群的丰度和相关性）和微生物（土壤微生物群落的进化水平）条件。
