Application of GIS technologies to implement environmental monitoring of laboratory studies of soils under power transmission lines in the Southern foothills of Fergana region

Abstract

Aim: The purpose of the study is to introduce GIS technologies and create digital maps of irrigated soils, databases for soil surveys and agrochemical properties of lands of protected zones of linear objects of the Fergana region, as well as to determine the influence of power lines on wheat yield. Methods: The article uses methods of spatial and system-structural analysis, cartographic, comparative-geographical, statistical, typological and natural-economic zoning. They are based on GIS technologies using modern technological software, such as ArcGIS 10.3(2), and SAS Planet 1.3. Mathematical statistical processing of research results was carried out based on the IRRISTAT program. Results: based on the new modernized method, irrigated soils of farms under power lines were evaluated, and digital attribute bonus maps were compiled. Scientifically-based recommendations aimed at improving soil properties and efficient use of land resources have been developed. Conclusion: Based on the results of research conducted based on GIS technologies, ArcGIS applications and the rules of direct genetic soil science, the influence of high-voltage electrical networks on the properties of the soil of electromagnetic fields and protection limits were determined. The definition of areas in the study area, the establishment of boundaries, the definition of zones of impact and protection of high-voltage electrical networks, the analysis of agrophysical, agrochemical and other soil properties, the ways of using attribute data from individual modern GIS technologists and ArcGIS applications have been improved and appropriate maps have been compiled.
