摘要
The purpose of this study is to produce an analysis of the urban expansion in the case of a mountain resort in the Romanian Carpathians through the integration of different cartographic and ancillary material in the remote sensing imagery processing. The spatial pattern analysis of the changes underwent by the urban landscape was based on multi-temporal information sources, covering 28 years, which highlighted the major turning points in landscape evolution, meaning industrial development under the communist production planning and residential expansion in recent years. To fully exploit the combination of satellite image processing in IDRISI, the manual image classification and database interrogation in ArcGis, we used a uniform grid, representing a set of vector data for each year available from the Landsat image archive. The image comparison was completed by using appropriate quantitative techniques. In conclusion the urban landscape evolution was linked to the socio-economic context. At a historic scale the main phenomenon identified is the concentration of mass tourism facilities, located in contiguity to a protected area, a situation reflected in the constant fragmentation of surfaces covered with vegetation at the urban fringe. In the digital earth science, the interplay between mountain ecosystems and human activities encompasses a key role in the management of viable mountain landscapes.
