Abstract:Kulturna krajina, ki je rezultat človekovega poseganja v naravo in urejanja z njo, se je na območju Movraškega Krasa in bližnjih flišnih predelih v zadnjih 200 letih korenito spremenila. V tem diplomskem delu je obravnavana problematika spreminjanja vegetacije — habitatnih tipov ter rabe tal na območju Movraškega Krasa in bližnjih flišnih predelov med leti 1830 in 2008. celotno območje s skupno površino 53,9 km2 je bilo kartirano po habitatni tipologiji PHYSIS v letu 2007. podatki so bili obdelani s programsko opremo ArcGis 9.2 in so prikazani na slikah ter v tabelah. Kartirane poligone smo v nadaljevanju združili v 8 kategorij: naselja in druga infrastruktura, njive, travniki in pašniki, gozd, vinogradi, vode, flišne erozijske oblike in skalovje, oljčniki in drugi nasadi — z namenom primerjave s historičnimi podatki. Izračunane izmere površin posameznih kategorij in površinski odstotek poligonov po posameznih kategorijah smo primerjali s karto »Carta Corografica del Litorale« iz leta 1830. Izstopajoč je proces zaraščanja kot posledica deagrarizacije, po drugi strani širjenje urbanih površin in objektov, zaraščanje travnikov in pašnikov, drobljenje in zmanjševanje njivskih površin. Pomemben vzrok za to je v spremenjenih socioekonomskih razmerah. Večje so spremembe v rabi tal na flišnem predelu raziskovanega območja v primerjavi s apnenčastim delom, kar si razlagamo z vododržnimi lastnostmi flišne kamnine.

Title:THE COMPARISON OF VEGETATION AND LAND USE IN MOVRAŽ KARST AN NEARBY FLYSCH AREA BETWEEN YEARS 1830 AND 2008
Abstract:Agricultural landscape, as a result of human interference and management, has drastically changed in the last 200 years within the area of Movraški Kras and adjacent flysch areas. In this work the changes in vegetation cover and habitat types, as well as land-use categories between the years 1830 and 2008 on the above- mentioned area were considered. The entire studied area of 53.9 km2 was mapped according to the PHYSIS typology in the year 2007. The data were elaborated with ArcGis 9.2 program package and are shown in the form of figures and tables. Mapped polygons were then aggregated into 8 categories: settlements and infrastructure, fields, grasslands, forest, vineyards, water, flysch erosion forms and rocks, olive grows and other orchards. The comparison with historical data from the “Carta Corografica del Litorale” were performed. The process of spontaneous reforestation (overgrowing) emerged as very pronounced. On the other hand the spreading of urban surfaces, grassland encroachment, fragmentation of fields contributed a great deal of changes. An important cause for this phenomenon could be fined in changed socio-economic circumstances. The changes are more pronounced within the flysch sub-area in comparison with the limestone one, mostly due to different, more favorable properties of the flysch substrate.
Keywords:habitat types, vegetation, GIS, overgrowing, land-use, Slovenian Istra.
