The Application of Climatological Data in the Determination of Climate Favourableness for the Forest Vegetation of Croatia

چکیده

The Meteorological and Hydrological Service in Zagreb has been monitoring the values of climatological elements and phenomena in the atmosphere and on the ground for a long period of time. A data bank has been established of exceptional value which is bcing used for research in natural sciences. The Forest Research Institute, Jastrebarsko, has produced the Pluviothermal climate favourableness indices for tbrest vegetation based on the Climate Atlas and the Institute data. l9 ditTerent clirnate t'avorableness indices in Croatia (KL-l to KL-19) and the index ofthe greatest favorableness have been determined on the basis ofa hypothesis that the most f'avourable climatic conditions donrinate on those areas where the biocoenoses membeis are the most numerous. This hypothesis has been confirmed by the central position of the best fhvourableness index (KL-10) in a sequence of l9 members. The indices distribution in Croatia has been shown on the map (scale l:1,350.000). The relative values ofthe indices have been determined by aftributing the highest value to the highest climate lavourableness index (KL-10) and the srnallest value to the lowest favourableness index (KL-l and KL-19).These indices can be applied to nunlerous natural science research fields and in forestry. Key word index": Clintatology, vcgetation, pluviothermal climate favourableness indices. Saietak DrZavni hidrometeoroloiki zavod u Zagrebu vei dugi niz godina trajno prati vrijednosti klimatskih elemenata i pojava u atmosfbri i na tlu. Ostvarenje lbnd podataka izuzetne vrijednosti, koji se koristi za prirodoznanstvena istraZivanja. U Suntarskom institutu Jastrebarsko, na osnovi Atlasa klime i podataka Zavoda, izradeni su Pluviotermidki indeksi povoljnosti klime za Sumsku vegetaciju. Utvrdeno je da u lJrvatskoj ima l9 razliditih indeksa povoljnosti klime (KL-l do KL-19), a indeks najveie povoljnosti je utvrden na temelju hipoteze da najpovoljnije klimatske prilike vladaju na onim prostorima na kojima je najveia,bro-inost dlanova biocenoze. llipotezaje potvrdena sredi5njinr poloZajenr indeksa najveie povoljnosti (KI--10) u nizu od l9 dlanova. Rasprostranienost indeksa u Hrvatskoj prikazanaje na karti u mjerilu l:1,350.000. Relativne vrijednosti indeksa utvrdenc su tako daje indeksu najveie povoljnosti klime (KL-10) dodijeljena i najveia vrijednost, a ostalim indeksima vriiednosti linearno i simetriino opadaju do indeksa najmanje povoljnosti (KL-l i KL-19). Indeksi se mogu primijeniti za brojna prirodoznanstvena istraZivanja, a u sumarstvu za utvrdivanje Zivotnih prilika iumskih staniSta.
