Abstract: There were agricultural climatic characteristic of high mean temperature, heavy rainfall, low sunshine and less temperature difference among day and night during winegrape ripening in Danfeng area. Sugar content was in accordance with "S" curve, while acidity showed with logistical curve. The difference of precipitation in growing period was main reason that caused difference of grape maturity among different years in this area. Liner regression of maturity on heat-coefficient could predict the maturity of different cultivars. Heat-coefficient was better index of variety-zoning in these regions and similar areas.
