摘要：Rila Mountain and Pirin Mountain (N 42.1°, E 23.5° and N 41.7°, E 23.4°) are the highest morphounits in the Balkan Peninsula. During the last Ice Age (Wuerm), their highest parts were subjected to an alpine-type glaciation. This led to the formation of various glacial landforms. The most expressive of them are the cirques. The main goal of the present study is to examine and evaluate the possible fractal geometry of 77 glacial cirques in Rila and Pirin Mountains. For this purpose is used the number / area method for estimating of surface fractals. This is the first investigation of this type for the study lands at all. The results obtained unambiguously confirm the fractal geometry of glacial cirques in the Rila and Pirin Mountains. This in turn provides new guidance in the analysis and interpretation of the relief building processes within the research area.
