Application of geoinformation systems in sounding the ecological and economic network of the urban environment in the northern territories

Abstract

Global climate change and its impact on the environment is one of the main problems of the 21st century. In the Arctic zone, where considerable oil and gas reserves are located, warming is 2-3 times faster than the world average. Against the backdrop of increased Arctic warming, thermal pollution has created permanent urban heat islands, where urban temperatures are  1-2 degrees Celsius higher than in surrounding areas. The aim of the article was a geoinformation assessment of climatic and anthropogenic characteristics in various zones of Tyumen (recreational zones (parks and reservoirs) and the zone of urban highways) in the summer of 2021. The Earth program was used in the studies, statistical processing of the results was carried out using the IBM SPSS Statistics 21 software.  It has been found that a circadian diurnal rhythm is observed both in recreational areas (parks and reservoirs) and in the area of urban highways (wind speed, temperature and relative humidity, concentration of CO, CO2, SO2, NO2) in the summer of 2021. The revealed correlation relationships between climatic characteristics and anthropogenic pollutants and aerosols indicate that global climate change is associated with the deterioration of the ecological situation in the urban environment and doesn't depend on the landscape features of the city.
