GIS-based assessment of the distribution of 2100 predicted changes of precipitations and influence on biodiversity and natural protected areas in Romania

摘要

Due to the environmental effects, clime changes constitute an important issue, particularly the assessment of their potential effects under different scenarios. This study considers the predictions for 2100 based on 2×CO2 concentration and the CCM3 model and attempts to investigate the effects over the Romanian territory, including the spatial distribution of high, average, and low differences between predicted and actual values by landforms, eco-, bio- and geodiversity as defined by the biogeographical regions and land use, and natural protected areas. The results indicate that the highest differences occur over the central and southern part of the territory, affecting a large part of the mountain area and important agricultural areas, as well as the natural protected areas situated at high altitudes.
