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.
