In Graduation thesis we were studying changes in basic and detailed land use in the municipalities of Cerklje na Gorenjskem and Preddvor. The changes of land use were established by comparison of municipal medium-term social plans (hereafter PS SDPO) and municipal spatial plans (hereafter OPN). Municipalities, their normative starting points and the content of PS SDPO and OPN were briefly presented. In the practical part, comparison of basic and detailed land use areas of the entire two previously listed municipalities, Cerklje na Gorenjskem and Preddvor, between PS SDPO (2004) and OPN (2014) is made. Data were processed and analyzed in ArcGIS 10.3 and Excell and displayed them in maps and figures. With the analize of studies changes of land use, we have found that the share of residential areas in both communities has increased. In Cerklje na Gorenjskem municipality it has increased for 2,02 % at the cost of agricultural land and in Preddvor municipality the increase was 0,19 % at the cost of agricultural and forest land.With the analysis of the area in terms of population in Cerklje na Gorenjskem municipality, we have found that increased number of residents coused residental space per capita to decrease for 31,39 m2. In Preddvor municipality we have come to the similar findings, except that the area of residental land per capita in predvor decreased for 31,79 m2.
