原始语种摘要: In the paper, the aridity is defined on the basis of four climate indices: DeMartonne's index of aridity, Lang’s Rain Factor and Gračanin’s Rain factorfor the vegetation period and hydrothermal coefficient of Seljaninov. Whilethe annual value of the drought index (IDM) shows humid characteristics, themonthly values show the variability of the conditions. The summer months(July and August) are classified as semi-arid months, while the wintermonths (December- February) are extremely humid. The spatial distribution ofthe isoarids indicates that the northern part of the basin has thecharacteristics of a semiarid climate, while the southeastern parts are morehumid. The analysis of mean annual values of the drought index indicates insemiarid conditions (1990 and 2000), but also the humid...
