Spatial distribution analysis of the ecological factors in the Avereşti Wine Growing Centre – Huşi vineyard

Abstract

The spatial distribution of the ecological factors explain the presence in viticultural areas of “terroirs”, which are microzones with particular ecological features, favourable for wine growing, that influence the quality of grapes, as well as the authenticity of wines. The locations of these terroirs in the vineyards are usually known, but their ecological evaluation and territory delimiting are difficult to achieve. In this work, we proposed the use of the Geographic Information System (GIS), a tool of the informational technologies that allow carrying out complex analyses of the geographic areas. Using GIS, we calculated the spatial distribution of some climatic (temperature, solar radiation, insolation and rainfall) and topographic factors (altitude, slope and slope direction) for the Avereşti Wine Growing Centre and elaborated the thematic maps corresponding to the abovementioned factors. Their analysis pointed out the presence in the Averesti wine growing area of many "terroirs" with particular ecological features, some of them being favourable for the production of quality white wines, while others, for table and sparkling wines.
