Red wine and dry white wine brewing grape planting climatic division in Hexi Corridor
Based on general survey of the related main meteorological factors in the fruit and quality forming period of dry-red wine and dry-white wine brewing grapes and climatic characteristic in Hexi Corridor, the ≥ 10℃ accumulated temperature, the mean temperature of the hottest month (July) and the daily range of temperature in ripening period (August- September) were selected as climatic division index system of Hexi Corridor, which were used separately with the geography factor to calculate the regression equation. Using the plat form of geographic information system Citystar soft ware Hexi Corridor was divided into five climatic regions, which were the most suitable region( elevation 1 400 ~ 1 750 m), the suitable region( elevation 1 300 ~ 1 400 m and 1 750~1 850 m), the less suitable region(elevation 1 130~ 1 300 m),the capable of planting region(elevation 1 864~1 990 m)and the unsuitable region(elevation >1 990 m).
