Abstract:
In this scientific paper are
presented the preliminary results of the
research having as goal to establish a
methodology for the determination of the
oenoclimatic potential and its spatial
distribution in the viticultural areas. Data
were obtained by means of GIS technology
and disclosed a new, original model for
analysing the viticultural ecoclimate. The
evaluation presented in this scientific paper
was the result of processing and interpreting
data concerning spatial distribution,
individual influence and total influence of
four ecological factors that determine the
quality of grapes: slope, aspect, solar
radiation and real insolation. Investigations
were carried out in three stages: I.
Determination of the spatial distribution of
ecological factors in the wine growing
region; II. Determination of the ecological
factors suitability and their distribution in
the wine growing region; III. Determination
of the oenoclimatic potential of the wine
growing region and the graphical
representation of its spatial distribution.
The distribution of ecological factors is
represented by digital maps. The ecological
factor suitability for grape growing was
assessed according to a new evaluation
system, and its distribution was represented
graphically on the region map. The
oenoclimatic potential was expressed by the
sum and the average of evaluation points
given to the ecological factors. We found
that the sum of evaluation points has
generated a detailed representation of the
oenoclimatic potential, while the average of
evaluation points gave a much clearer
synthetic representation, allowing the
identification and delimitation of highly
favourable terroirs. The evaluation of the
Avereşti wine-growing centre – Huşi
vineyard (Vaslui County) has shown that
94.37% of its area was favourable for
producing high quality white wines, 4.40%
for producing quality white and red wines,
while 1.19% was less favourable for wine
growing. The maps showing the distribution
of the oenoclimatic potential highlighted the location of valiant terroirs in the Avereşti
wine growing centre.
