Rezumat

These studies are conditioned by the lack of extensive meteorological stations network of on the territory of the Republic of Moldova, as well as the orographic conditions expressed by frequent alternations of hills with depressed landforms determine the great climatic variability on concrete territories. That is why the research required climate interpolations, the latter being possible thanks to the development of Geographic Information Systems. The information layers within the ArcGIS Program, developed for each separate physical and geographical factor (latitude and longitude, relative and absolute altitude, slope orientation and slope, etc.) together with the regression models calculated under the Statgraphics Centurion XVI Program, were on the basis of digital maps elaboration, that reflect the current state of the climate - for Ialoveni administrative district, as well as the climate forecasted for the coming decades in this area. The elaboration of the digital maps took into account the quality of the model obtained in its entirety, as well as the level of significance of each important physical-geographical factor that contributes to the redistribution in space/territory of the climatic parameters under study. We report that within the limits of Ialoveni district the altitudes are about 31 - 316 m, and the majority orientation of the slopes is northwest, northeast and southeast, with a degree of inclination of up to 100.
For the first time, at the level of the administrative district, the particularities of the current climate and those predicted in the coming years, according to climatic scenarios presented by the Intergovernmental Commission on Climate Change, were identified. A set of digital maps of thermal regime and precipitation was developed, characterizing the annual and seasonal climate, obtained as a result of modeling both the modern climate and using the RCP4.5 projection, which emphasize spatial differences depending on the absolute height, orientation and degree of slopes inclination. Considering, the need to use the results obtained in the development of the Ialoveni district to restore the ecological balance, the results obtained were presented to the regional council for inclusion in the future development strategy, confirmed by a Сertificate of Incorporation.
