Abstract. The scope of the paper is the current radioecological situation on the Kola Peninsula. Activity of existing enterprises in the region increases the potential danger of radioactive contamination. One of such enterprises is the ship reparation yard Nerpa specializing in the disposal of decommissioned nuclear submarines of the Russian Federation Navy since 1992. The aim of the study is to determine the degree of Nerpa influence on the environment by investigation of spatial distribution of 137 Cs in the upper soil horizons and lichens as the most reliable indicator of radioactive contamination.
Intensive urban and economic development leads to changes in functional planning of the territory. Comprehensive study of the existing use and ecology of the urban environment is necessary for making decisions on urban space optimization. This study can detect the negative effects of human impact and solve social and economic problems within the city. The socio-ecological assessment of the urban area within the developing zone carried out on the ground of the GIS, developed and compiled by the authors. The database of GIS consists of six blocks, including cartographic and attribute information with characteristics of the environment, functional planning and socio-demographic features of the territory.
