Abstract:
The paper presents the
results of a study regarding the spatial
distribution of slope exposure and slope
inclination in Husi vine growing centre,
Husi vineyard. These factors determine the
ecological suitability of an area for vine
growing and influence, to a large extent,
both directions of wine production and
grape quality. The knowledge in their share
and variation in vine growing areas, allows
to establish the proper grapevine varieties,
to place each variety in the optimum
location (microzoning), to choose the
optimal training system and the appropriate
maintenance techniques for the vineyard
area. The technology that allows such
analysis and the elaboration of maps with
spatial distribution of the ecological factors
is GIS (Geographic Information Systems),
an instrument of information technologies
introduced in the last years in viticulture
too. The research presents a case study in
which GIS is used to determine the
geomorphological features of Husi vine
growing center, the local variation of the
slopes and the spatial distribution of
ecological suitability in the vineyard,
depending on these factors. The results
show that, in relation to suitability of slope
inclination and slope exposure, Husi center
includes four areas with different suitability
for vine growing. Of the total vineyard area,
42.2% (903.2 ha) has south and
predominantly south exposure, the most
favorable for vines, and 37.98% (814.58 ha)
northern exposure, bad or limiting for vines.
The slope analysis shows that 29.19%
(624.2 ha) is suitable for high production
varieties, and 70.81% (1515.6 ha) for
quality wines varieties. According to the
suitability of slope inclination and slope
exposure, the most favorable for vine
cultivation is SD4 area, that includes Recea
and Galbena lands, while the worst for the
vines is SD1 unit that includes Rusca, Schit
and Ochi lands.
