Abstract: Based on observed meteorological data of 15 stations in west of Guizhou province from 1978 to 2010, by using of GIS technology, the climatic division for spring potato was developed. The results showed that 8 indices to climatic division for spring potato existed. They were altitude, average temperature and  active accumulated temperature above 10℃and precipitation and sunshine hours in growth stage, average temperature in July, the average temperature difference between day and night from July to August and precipitation from May to July. Division was under grid interval of 100m×100m, and got 52% most suitable area, 45% suitable area and 3% subsuitable area in west Guizhou province.

Key words: GIS, Climate suitability, Regionalization, Spring potato, Western Guizhou
