RAZVOJNO-VAROVALNI POMEN POKRAJINSKO-EKOLOŠKE SESTAVE SLOVENIJE Dušan Plut Dr., Oddelek za geografijo, Filozofska fakulteta Univerze v Ljubljani, Aškerčeva 2, 1000 Ljubljana, Slovenija e-mail: dusan.plut@ff.uni-lj.si Izvleček Raznolika pokrajinskoekološka sestava Slovenije je v preteklosti pomembno vplivala na prostorsko razporeditev prebivalstva, dejavnosti ter pokrajinsko rabo. V agrarni in industrijski družbi so bile v ospredju različne oblike izkoriščanja pokrajinskoekološkega potenciala Slovenije. Postindustrijsko obdobje pa zaradi prekomerne rabe naravnih virov in obremenjevanja občutljivih pokrajinskoekoloških sestavin prinaša potrebo po varovalno in razvojno uravnoteženi rabi pokrajinskoekološkega potenciala Slovenije. Sonaravni model prostorskega in regionalnega razvoja Slovenije se lahko uresniči zgolj ob upoštevanju njene raznolike po-krajinskoekološke sestave. Ključne besede: pokrajinskoekološke sestavine, pokrajinskoekološka sestava, razvojno-varovalno načrtovanje, sonaravni razvojni model, Slovenija DEVELOPMENTAL-PROTECTIVE ROLE OF THE LANDSCAPE-ECOLOGICAL COMPOSITION OF SLOVENIA Abstract The varied landscape-ecological composition of Slovenia had a significant impact in the past on the areal distribution of the population, activities, infrastructural network and landscape use. In the agrarian and industrial societies the landscape-ecological potentials of Slovenia were exploited in a variety of ways. Due to the excessive exploitation of natural resources and the burdening of sensitive landscape-ecological components in the postindustrial society, it has become urgent to use the landscape-ecological potential of Slovenia in such a way that protection and development be balanced. The sustainable model of spatial and regional development of Slovenia can only be implemented if its diverse landscape-ecological components are taken into account. Key words: landscape-ecological components, landscape-ecological composition, developmental-protective planning, sustainable developmental model, Slovenia.
