THE SPATIO-TEMPORAL ANALYSIS OF IMPERVIOUS SURFACES IN CLUJ-NAPOCA, ROMANIA

Kinga IVAN

ABSTRACT: The remarkable increases of impervious surface areas are associated with urban land cover expansion and population growth. In the present study I intended to offer a retrospective look at urban land cover growth, particularly the extent of impervious surfaces, for a period of 28 years (1986-2014). The impervious surfaces for the reference period was analyzed using Landsat satellite imagery and the supervised classification method of Maximum Likelihood. Results showed an expansion of impervious surfaces from 33% in 1986 to 40% in 2014 and a population growth rate of 3% from 1986 to 2014. During the study period, impervious surfaces spread significantly in the southern and eastern parts of the city and more moderately in the northern parts.
