Abstract: Based on the previous studies, an ecological zoning index system of Cabernet Sauvignon was established. Using step by step method and optimization method, the authors studied the ecological regionalization of Cabernet Sauvignon in northern China and made a regionalization map by support of GIS technology. The results showed that, in northern China, the ecological region of Cabernet Sauvignon can be divided into five categories: most suitable, suitable, poorly suitable, not suitable and not plantable. The most suitable ecological area of Cabernet Sauvignon, as a midlate maturing variety, was scattered in northern China with small areas, and was mainly distributed in Northwest China. Suitable ecological area was more widely distributed, including Northwest China, Northeast China and central plains, covering the major wine grape producing areas. The raw material base of Cabernet Sauvignon should be firstly established in the most suitable areas and suitable areas, secondly in the poorly suitable region, trying to avoid to  establish in not suitable areas and not plantable areas. The results provided a reference to the wine grape industry development planning and wine grape base layout.
