Abstract:Energija sonca napaja ekosisteme na zemlji, zato so meritve sevanja temelj ekoloških raziskav v gozdovih. Vsaj osnovne zakonitosti porazdelitve sevanja v vegetaciji mora poznati tudi praktik gojitelj. Na področju meritev sončnega sevanja smo priča hitremu razvoju metod in instrumentov. Prispevek uvodoma predstavlja sončno sevanje kot enega najpomembnejših ekoloških dejavnikov ter njegov pomen za gojenje gozdov. Osrednji del članka predstavlja in ocenjuje uveljavljene metode za merjenje in ocenjevanje sončnega sevanja v gozdovih. Na podlagi primerjave metod ugotavljamo, da je za zahtevnej{e raziskave gozdne vegetacije zelo primerna uporaba več PUR (Photosynthetically Usable Radiation - fotosintetsko uporabno sevanje) tipal, krmiljenih z računalnikom. Obetavno bodočnost ima tudi metoda ocenjevanja sevanja z analizo fotografije nebesnega svoda. Na tem principu deluje tudi stabilni horizontoskop, katerega uporaba je še posebej priporočljiva za praktično gojenje gozdov.

Title:Solar radiation measurements in forest- I. evaluation of methods and instruments
Abstract:Solar energy sustains ecosystems on earth, therefore solar radiation measurements are the basis for ecological research in forests. Silviculturistsin particular should be aware at least of the basic principles of radiation distribution in forest vegetation. There has been a rapid development of methods and devices in the field of solar radiation measurement. In the paper, solar radiation is presented as one of the most important ecological resources and factors. The author demonstrates how significant this knowledge is in silviculture. The main topic is the presentation of recognized methods for solar radiation measurement and estimation in forests. Comparing these different methods we find Photosynthetically Usable Radiation (PUR) sensors to be very appropriate for complex research in forest vegetation. It is advantageous to use multiple PUR sensors connected to a computer for data processing. Another method for estimating radiation which has great potential is the one using hemispherical photography. The same principle is applied in a fixed horizontoscope which is particularly appropriate in silvicultural practice.
Keywords:solar radiation, radiation measurement, silviculture, photosynthesis, photosynthetically active radiation, photosynthetically usable radiation
