Soil Diversity and Key Functional Characteristics of Yakutsk City: Largest Urbanized Cryogenic World’s Ecosystem

Urban soils are the most vulnerable component of current terrestrial ecosystem. Due to anthropogenic influence, various pollutants can accumulate in and have a negative effect on health citizens. As result degradation permafrost landscapes, disappearance number natural ecosystems, as well urban areas, is possible. In course development thermokarst processes, problems arise environment with destruction buildings decrease agricultural areas. The ecosystem Yakutsk city located valley Lena River represents largest urbanized biotope, permafrost-affected bioclimatic geogenic conditions. This work relevant datasets physico-chemical, toxicological agrochemical state soil cover components functional zones city. An 3excess maximum threshold levels for Zn was noted area active mining within borders. From data obtained pollution state, polluted zone quarry complex relative proximity other studied areas city, there no excess permissible trace elements. According analysis, relatively low content available elements comparison cities zone.
