Abstract

Gradually, the study of the landscape became a core topic of environmental studies, due to its interdisciplinary research methods, integrating both natural and socio-economic data. The goal of the study is to quantify the structural evolution of Bistrita subcarpathian valley landscape, by using several GIS applications, having an important role in highlighting its functionality. The applications were realized for the extended area limit of Bistrita subcarpathian valley, which presents a complex landscape morphology, with features ranging from forested mountains to densely populated lowlands. The analysis was based on the two land cover maps resulted from the extraction of the spatial layers from the 1986 cadastral plans, 1:10.000 scale, respectively the 2005/2006 ortophotomaps, 1:5.000 scale. For completing the study, were calculated for the two periods a series of specific indicators, called landscape metrics, which contain quantitative information about the structure and features of the landscape. The results of the analysis proved the utility of these indicators in quantifying the structural evolution of the landscape, and also highlighted the capabilities of using Open Source software for complex spatial analysis. This type of analysis has a great importance for the authorities and other decision making factors regarding the territorial planning processes.
