Abstract: The development of wine industry is greatly influenced by the market in China, being not perfect. Planning and regionalization for production areas are one of the main ways to promote ecological development of wine industry. Comprehensively using the methods of fuzzy mathematics, optimization and stepwise division, the ecological regionalization for dry red wine grape varieties in northern China where dry red wine dominates the wine industry was completed with small grid simulation methods, spatial analysis and layer operation supported by GIS. The results showed that the most ecologically suitable areas of dry wine grape varieties distributed in the following areas: the south section of Daxinanling Mountains region, counties in Western Liaoning Corridor region; most areas of Shangdong Peninsula surround the Bohai Gulf, Qinhuangdao districts and most of Liaodong Peninsula; most of Zhangjiakou and Datong in the border areas of Hebei and Shanxi provinces; the areas on the two sides of Helan Mountain and along the Yellow River in the northwestern region of China; areas in the Yili Valley and along the eastern Tianshan Mountain in Xinjiang.
