我国北方不同熟性酿酒葡萄的生态区划

Ecological regionalization for different maturity wine grapes in northern China

结合已有研究成果,分别建立了不同熟性酿酒葡萄的生态区划指标体系,采用逐步分层法和集优法相结合的方法,在GIS技术的支持下,开展了我国北方不同熟性酿酒葡萄的精细化生态区划。结果表明,我国北方早、中、晚熟酿酒葡萄的最适宜生态区均呈零星分布,面积较小,并且其区域基本不会互相重叠。早、中、晚熟品种的适宜区分布均较为广泛,虽然相互间略有重叠,但大部分地区有所差异;某一特定的区域很难既是早熟品种又是晚熟品种或者是中熟品种的最适宜生态区。在中国北方进行产业布局和原料基地建设时,需要充分考虑不同熟性酿酒葡萄对生态因子的特殊需求,科学论证,合理布局,确保将不同熟性的品种种植在其优质生态区内。

Based on previous studies, an ecological zoning index system of different maturity wine grapes in northern China were set up. Using the step-by-step stratification method and set optimi- zation method, the authors studied ecological regionalization of different maturity wine grapes in northern China and made the regionalization map by support of GIS technology. The results showed that, in northern China, ecological area of early-, mid- and late-maturity wine grapes can be divided into 5 categories： the most suitable, suitable, poorly suitable, not suitable and not planting. The most suitable ecological region of different maturity wine grapes were scattered in small areas, and not overlapped. The suitable areas are more widely distributed; although they were slightly overlapped, most of the areas were different. It is almost impossible that a given ar- ea is the most suitable ecological region for both early maturing varieties and late maturing varie- ties or mid maturing varieties. In wine grape industrial layout and raw material base establish- ment, the special needs of different maturity grapes for ecological factors should be considered, to ensure that the different maturity varieties are grown in the most suitable ecological zone.
