Abstract

The methodological approaches to create a technology of geoecology assessment of urbanization areas were considered in the article. Mytishi and Khimki urban districts were taken as examples of dynamic development city districts in north part of near Moscow vicinity. These methodological approaches were used to green areas which most important for ecological wellbeing in urban areas. The satellite pictures and results of instrumental investigation were used as importance parts this technology. We used Landsate-7 and Landsate-8 satellite pictures 2000, 2010 and 2018 years and assessed the dynamics different classes of objects and fragmentation these districts. The decrease of forest and open biotopes were showed. The temp development of open biotopes during the period decrease too. The north part of near Moscow vicinity is comparable with cities EU by degree of fragmentation. The trees are important barrier in road to distribution of pollutants in city condition. Therefore, second part of geoecology assessment included ecology-geochemical investigation city parks and squares. The results of analyses chemical elements in birch leaves and topsoil were used as criterion. The samples were taken from green areas of biggest cities northern part Moscow vicinity. We have revealed an excess MAC on Cu and Pb. Nevertheless, there are relatively low contents analyzed elements in (Cu, Zn, Pb, Cd, Ni, Cr, Sr) in birch leaves. Our results well assessed an air quality in lower layer in green areas.
