摘要:Within the Carpathians, the Southern Carpathians are located in the South part and contains the largest number of peaks situated at over 2500 meters altitude. Aspen (Populus tremula L.) is a pioneer species with a rapid growth, usually found in the temperate and boreal areas from Eurasia. In our country, the species is present in hill and mountain areas, up to 1600 m in altitude and in mixture forests. The purpose of this article is to analyze aspen strands from the Southern Carpathians from the point of view of site and growth conditions. In order to achieve this, we have used data from forest management plans realized during 1982 - 2006 for 35 forest districts located in this area. The stand and site characteristics that were analyzed were the following: location, pruning, current growth, production class, structure, slope, exposition, altitude and forest type. The surface occupied by aspen stands in the Southern Carpathians is of 2302 ha, with the majority located in the southeast part. Aspen stands from this area are characterized by a mixt or intimate mixture, low pruning, current growth of 0.4- 0.8 m3 /year/ha, medium and inferior production classes, and an even-aged, relatively even-aged and relatively unevenaged structure. They vegetate on fields with a high or very high slope, at average altitudes between 700 and 1100 m, in mountain common beech stands or fir, Norway spruce and common beech mixtures.
