Prirodno-geografska obilježja otoka Silbe

Otok Silba u zadarskom arhipelagu, u prirodno- geografskom smislu, vrlo je osebujan i zanimljiv. O njemu je pisano u više navrata, a u ovom prilogu predstavljena su novija saznanja o površini, obuhvatu, geološkim i geomorfološkim, te pedogeografskim, hidrogeografskim i klimatsko- geografskim obilježjima ovog otoka. Spada u male hrvatske otoke, a pripadaju mu još tri otočića (Grebeni) i dva grebena unutar mjerničke općine, i jedan otočić (Grujica) u susjednoj k. o. Premuda. Hipsografski otok nije istaknut, a obale su uglavnom stjenovite i niske, s više privlačnih uvala i žala. Istaknuta krška osnova omogućuje stvaranje samo plićih tala u čemu i klimazonalni prostor pravog Sredozemlja te oskudica voda na površini imaju značajnu ulogu. Malobrojne pojave vode u prošlosti su imale veliko značenje za život i opstanak stanovništva. S visokom insolacijom, umjerenom naoblakom, uglavnom zimi, ugodnim temperaturama, razmjerno malim temperaturnim kolebanjima i rijetkim pojavama snijega, leda i mraza, s tek nešto jačom vjetrovitošću zimi, Silba je prostor ugodnog, pravog sredozemnog podneblja, što se odražava i na raširenost domaćeg klimazonalnog raslinja. U uvjetima suvremene preobrazbe načina života i promjena u krajobrazu s napuštanjem tradicionalne poljoprivrede i jačanjem turizma, rješavanje vodoopskrbe jedno je od najvažnijih pitanja daljnjeg razvoja otoka čija su prirodno geografska obilježja bitan čimbenik njegova opstanka i nadaleko poznate privlačnosti, kao i osnova budućeg razvoja. - Silba island in the Zadar archipelago, according to its natural geographical sense, is very peculiar and interesting. About the island there are some literature written on several occasions. In this paper recent results on surface coverage, geological, geomorphological pedogeographical, hydrogeographical, and clima-geographical features of the island have been presented. Silba belongs to the small Croatian islands, and it includes three islands (ridges Grebeni) and two reefs within the cadastal municipalitiy, and one island (Grujica) in the neighboring c. m. Premuda. Hypsography of the island is not stressed, and the shores are mostly low and rocky, with many attractive bays and beaches. Prominent carstic litology enables only shallow soils, in which the climazonal area of Eumediterranean and the scarcity of water on the surface, play a significant role. Scarce water sources in the past have had great meaning for life and survival of the population. With high insolation, moderate cloudiness, mainly in winter, pleasant temperatures, a relatively small temperature variations and rare occurrences of snow, ice and frost, with only slightly stronger winds in winter, Silba is the is pleasant space of a real Mediterranean climate. This reflects in the prevalence of domestic climazonal vegetation. In terms of contemporary lifestyle transformations and changes in the landscape with the abandonment of traditional agriculture and strengthening of tourism, water supply solving is one of the most important issues of further development of the island, whose natural geographical features play an essential role in its survival and well-known attractivity, as an important basis for the future development.
