Mapping viticultural potential in temperate climate ares, case study: Bucium vineyard (Romania)

anglais. The paper presents the spatial distribution of ecological suitability for grape growing in Bucium vineyard (Romania), viticultural area with ecological characteristics representative for northern vineyards. The study is based on a complex methodology implying use of remote sensing, Geographical Information Systhems (GIS), climatic data, topographic and pedologic maps. Research reveal the low ecological potential of Bucium area, specialized, traditionally, in white table wines, sparkling wines and white quality wines. Data analysis shows that 30% of Bucium vineyard (281 ha of 928 ha) is inappropriate, in terms of climatic suitability, for vinifera varieties culture; 34% of the area (316 ha) has limited ecological potential, enough to produce white table wines and sparkling wines; 36% of the area (331 ha) is suitable for quality white wines. In the vineyard area was not registered suitable conditions for quality red wines production. Huglin’s heliothermal index values shows that the vineyard has climatic characteristics that allow culture of wine varieties with early and medium ripening. In terms of ecological suitability, it appears that the most favorable conditions offer Cetatuia wine land, the eastern slope of the Doi Peri hill, eastern slope of Visani hill, south-western slope of Bucium hill and southern slope of Pietraria wine land.

Lucrarea prezinta distributia spatiala a favorabilitatii ecologice pentru cultura soiurilor de vin in centrul viticol Bucium-podgoria Iasi, areal cu caracteristici ecologice reprezentative pentru podgoriile septentrionale. Cercetarea se bazeaza pe o metodologie complexa, in cadrul careia se utilizeaza imagini din satelit, Sistemele Informationale Geografice (GIS), date climatice, harti topografice si harti pedologice. Rezultatele cercetarii releva potentialul ecologic limitat al arealului viticol, specializat, in mod traditional, in producerea vinurilor albe de masa, vinurilor spumante, vinurilor aromate si vinurilor albe de calitate. Din analiza datelor rezulta ca 30% din suprafata analizata (281 ha din 928 ha) este improprie, din punct de vedere climatic, pentru cultura soiurilor vinifera; 34% din suprafata (316 ha) are potential ecologic limitat, suficient doar pentru producerea vinurilor albe de masa si vinurilor spumante; 36% din suprafata (331 ha) are potential pentru producerea vinurilor albe de calitate. In arealul viticol nu se inregistreaza conditii favorabile obtinerii vinurilor rosii de calitate. Valorile indicelui heliotermic Huglin, a carui distributie spatiala este prezentata in lucrare alaturi de amplasarea zonelor afectate de ingheturi si brume, releva faptul ca, in areal, exista conditii favorabile pentru cultura soiurilor cu maturare timpurie si mijlocie. Din punct de vedere al favorabilitatii ecologice pentru cultura soiurilor de vin, rezulta ca cele mai valoroase microareale sunt: plaiul Cetatuia, versantul estic al dealului Doi Peri, versantul estic al dealului Visani, versantul sud-vestic al dealului Bucium si versantul sudic al plaiului Pietaãria.
