Abstract

The article is devoted to geoinformation mapping of the ecological and magnetic state of soils in the city of Krasnokamsk. The study included point determinations of the volumetric magnetic susceptibility of soils and the concentration of heavy metals, followed by mathematical-cartographic modeling of the results obtained. Mapping the magnetic susceptibility of soils makes it possible to form areas of the ecological and magnetic state of soils, along which samples are taken for the determination of heavy metals. Thus, the sample size of soil samples for heavy metal studies is reduced without a significant decrease in the representativeness of the final results, which determines the relevance of the studies performed. The purpose of the research is geoinformation mapping of the ecological and magnetic state of soils in the central part of the city of Krasnokamsk. The boundaries of research from the south are limited by the industrial zone of the city, which is mainly represented by pulp and paper industry enterprises. In the eastern part of the survey area, Zakamskaya CHPP-5 and a machine-building plant are located. The soil cover of Krasnokamsk is represented by urbanozems and technogenic surface formations. The total number of magnetic susceptibility measurement points was 77, and heavy metals were determined in 10 samples. During processing spatial data, the methods of mathematical-cartographic modeling, spatial overlay and binary classification were used. The interpolation was performed by the geostatistical method ordinary kriging using the Spatial Analyst tool of the ArcGIS 10.8 program. The creation of the Web GIS “Geoinformation system of magnetic susceptibility and heavy metals in the soils of Krasnokamsk” was performed on the basis of QGIS open geotechnologies using the qgis2web tool, the VS Code code editor. The Web GIS is hosted on the free GitHub platform. Based on the results of mapping, soil contamination with nickel and copper was established. The total area of pollution was 0.55 km2.
