ANALIZA KLIMATSKIH PRILIKA KAO EKOLOŠKOG FAKTORA OD UTICAJA NA PREŽIVLJAVANJE BILJAKA U KULTURAMA PEŠTERSKE VISORAVNI
THE EFFECT OF CLIMATIC CONDITIONS AS AN ECOLOGICAL FACTOR ON PLANT SURVIVAL IN PEŠTER
Ratknić, Mihailo
Dražić, Milutin
The analyse of average annual and monthly values of temperatures and precipitation has not pointed at the intensity and periodicity of drought intervals with negative ecological effect. However, the analyse of a round of days without precipitation during the vegetation period together with the analyse of preoipitation values according to Thorthweit have shown that droughty years lasted from 1981 to 1986. A very strong drought was recorded in 1985 with 153,6 mm of moisture deficit from July to October in continuity. The strong drought continued in 1986 with 58,8 mm of moisture defioit during August and September. The moisture surplus during vegetation period has not been recorded in any of analysed droughty years. The results has shown that the climate of Pešter behaves as a very important ecofactor which badly influences the reafforestation success of reclamated shallow and skeletal lands so that the choice of species should bi determined according to the most unfavourable years and with the application of those af forestation techniques that mostly help the accumulation and preservation of atmospheric woters.
