| Sumario: | The knowledge of current conditions and recent changes in urban vegetation cover has begun through the analysis of temporal variability of the "normalized difference vegetation index" (NDVI) of four forested cities, comparing the images provided by satellite data for the summer periods 1986-2011. Methodologically, a preliminarycomparative analysis of correlations and trend estimation was carried out, of importance for understanding the interrelationship between urban morphology and green infrastructure.The results obtained indicate a general decreasing tendency of mean NDVI values. In the Turin metropolitan area, the index variation was not significant. Negative correlations were determined between NDVI and population, moderate negative correlations between NDVI and the size of the metropolitan area; while preliminarycorrelations between NDVI and climate variables did not follow the same scheme in the different metropolitan areas.In the future, it is hoped to define criteria of urban design appropriate for forested cities, which will enable the sectors responsible for the protection of the habitat to manage, design and implement feasible design responses towards the future, within the framework of urban and environmentally sustainable energy development. |
