COMPLEX ANALYSIS SYSTEM FOR SPATIAL DISTRIBUTION OF ECOTOXICANTS IN SOIL AND PLANTS

Abstract

This utility model relates to environmental monitoring, agroecology, and geoinformation technologies and is designed for a comprehensive analysis of the spatial distribution of ecotoxicants in soils and vegetation. The technical challenge lies in the insufficient integration of laboratory analytical data with spatial referencing and geoinformation modeling, which complicates the identification of patterns in the migration, accumulation, and transformation of ecotoxicants in agricultural landscapes, as well as complicates environmental risk assessment and management decision-making. The system for comprehensive analysis of the spatial distribution of ecotoxicants in soils and vegetation comprises a sequentially connected data collection and input unit (A), a processing and spatial analysis unit (B), and a visualization, storage, and decision support unit (C).Block (A) includes a laboratory data input subsystem, a subsystem for coordinate referencing of sampling points, a subsystem for inputting agrochemical and background characteristics, a subsystem for importing remote sensing and cartographic data, and a regulatory reference database, the outputs of which are connected to the input of block (B). Block (B) includes a geoinformation analytical module with sequentially connected subsystems for data storage and structuring, data preprocessing, spatial interpolation, mathematical modeling, and correlation analysis and environmental risk assessment. Block (C) includes a visualization subsystem and a territory zoning subsystem, connected to a subsystem for generating analytical reports, a data storage and archiving subsystem, and a user web interface.The system integrates laboratory data on ecotoxicant concentrations with coordinates of sampling points, performs spatial analysis of pollutant distribution across the study area, generates zoning maps based on environmental risk levels, and displays the relationship between ecotoxicant levels in soils and vegetation in a single geographic information system with an updated database. The technical result is improved accuracy in identifying pollution zones, provides a comprehensive spatial assessment of the relationship between ecotoxicant levels in soils and vegetation, and enhances the effectiveness of environmental monitoring and land quality management.This technical result is achieved through structurally and functionally interconnected units (A), (B), and (C), connected via wired or wireless digital data transmission channels. This enables the integration of chemical analytical indicators with spatial layers of the geoinformation environment, the calculation of integrated pollution indices, the creation of ecotoxicant distribution maps, the zoning of territories by environmental risk levels, and the generation of recommendations for users. This utility model can be applied in the state environmental monitoring system, agrochemical services, in scientific research on soil degradation, as well as in precision farming and the assessment of the environmental safety of agricultural territories.
