【 摘 要 】

The article presents the data of ecological monitoring and assessment of soils of the ecosystems represented in Kursk. On the basis of the description of the structure of 17 soil profile cuts laid out in different functional zones and geomorphological elements of urban landscapes, 7 main types of soils mainly represented in the ecosystems of Kursk were identified and depicted on the map-scheme. According to the monitoring of heavy metals, a tendency to the increase of the concentration of their gross forms in soils has been noted. The increase in their content reaches up to 48.9 % per year. Changes in the concentrations of mobile forms are determined by the dynamics of soil processes and, consequently, they do not always have increasing tendency. The soil remediation technologies, adapted for urban environment, are proposed. Phytoremediation technology and sorption method of detoxification helps to increase the environmental comfort in cities significantly.
