20.500.12556/RUL-68526 Spremljanje razvoja sestojev in časovna dinamika propadanja dreves v jelovo-bukovem gozdu Observation of the development of stands and chronological dynamics of forest decline in a beech and silver fir forest Leta 1985 smo s fotointerpretacijskim in terenskim snemanjem integralno analizirali stanje jelovo-bukovih gozdov na visokem krasu. Po delni ponovitvi aerosnemanja v letu 1988 smo oblikovali metodo za spremljanje razvoja sestojev in oceno sprememb poškodovanosti dreves. Rezultati parnih primerjav dreves, opravljenih s fotointerpretacijo infrardečih barvnih letalskih posnetkov in terenskim snemanjem v kontrolnih sestojih, kažejo, da v triletnem obdobju ni bilo velikih sprememb. Prevladovala so drevesa, kjer se poškodovanost ni spremenila, saj smo spremembo stanja krošnje določili pri 11 % jelk in smrek v vzorcu. Razlike med sestoji nakazujejo, da je podoba današnje poškodovanosti tudi posledica preteklega razvoja sestojev in različne intenzivnosti gospodarjenja. In 1985 the condition of forest belonging to plant association Abieti-Fagetum dinaricum on a karst plateau was analysed by photo-interpretation and a field survey. The aerial survey was partially repeated in 1988. Then a method for the observation of the development of stands and for the estimate of changes in damaged trees was designed. The results of a chronological comparative analyses of the same trees, which was performed by photo-interpretation of colour infrared aerial photographs and a field survey in control stands, indicate that there were no considerable changes in the degree of their damage in the three-year period. Changes in crown condition of trees were identified only in 11 % of silver fir and Norway spruce trees of the sample. The differences in the condition of stands indicate that the current damage results partly also from the development of the stands in the past and the degree of intensity of their management. propadanje gozdov fotointerpretacija Picea abies Picea excelsa forest decline aerial photographs Abies alba Picea excelsa true false false Slovenski jezik Angleški jezik Znanstveno delo 2015-07-10 21:07:04 2015-07-10 21:07:04 2024-08-09 03:46:42 0000-00-00 00:00:00 1991 0 0 Str. 55-96 Št. 38 1991 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*58 0351-3114 36009728 ZbGL-38-4.pdf ZbGL-38-4.pdf 1 BB4EAE2C3DB2A8A124F0FC319B2A6F64 91cfd771e49309fb367dfdaec85367d7ad3f6ffba5b32b57da8b9fae3c309b28 63c29d53-a1b3-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=100769 Biotehniška fakulteta 0 0 0
