o:1577 The satellite photos of the high resolution in the definion of the changes in the ecosystems using en ABSTRACT The adequate biodiversity protection at the species and genetic level is not possible without the adequate site protection. The climate change causes the increase in the air temperature (increased evapotranspiration), decrease in the quantity of precipitation, as well as the deterioration of the soil physical characteristics. The deterioration of the water-air soil characteristics will lead to the deterioration of the structure caused by the decrease of the nutrient content. The protective role of the vegetation will be reduced; the soil erodibility will increase, as well as the number of the wildfires, whereas the site conditions will deteriorate drastically. The global changes also affect the smaller regions, owning to which the monitoring of them is of a particular importance for the changes in the ecosystems. For this purpose we use the satellite photos of the high resolution, and by the use of GIS technology the method of the monitoring of the periodical changes in the ecosystems was developed. The collected data will enable the creation of the model which contains the dynamics of changes in the natural ecosystems. This paper analyzes cadastral municipality Djurašiši. The classification based on EUNIS system of the site classification was applied. By the use of the satellite photos of the high resolution (pixel size 1m) for Djurašiši area the spatial distribution of the sites was defined. By the periodical recording of the characteristic areas in Serbia the spatial distribution of the ecosystems, as well as the changes in their composition and structure, will be monitored. ecosystem, biodiversity, climate change, site, GIS 1552100 978-86-911273-4-3 1552102 https://www.researchgate.net/publication/261612402_PROCEEDINGS_The_1st_International_Congress_on_Soil_Science_XIII_National_Congress_on_Soil_Science 2023-04-06T09:57:57.450Z 44 yes 46 Михаило Раткнић 46 Соња Брауновић 0000-0002-1387-6955 46 Татјана Раткнић 46 Милета Бојовић 2014 application/pdf 1049178 https://unilib.phaidrabg.rs/o:1577 no yes 1 70 92000001 Proceedings of the First International Congress and XIII Congres in Soil Science of Serbia 711 723 Soil science Institute 2013
