宁夏酿酒葡萄气候区域化初探

通过对宁夏的气象资料（1996～2004年）进行统计分析，以酿酒葡萄生长期（4～10月）的活动积温为一级指标，葡萄浆果采收前2个月（8月、9月）的水热系数作为二级指标，将宁夏酿酒葡萄种植划分为12个栽培区域；综合分析影响酿酒葡萄品质的气象因子，认为兴仁、同心、韦州、麻黄山等以北的地区是发展酿酒葡萄的适宜区域，其以南地区因为活动积温不足，干旱、冰雹、霜冻等自然灾害频发等因素，难以进行酿酒葡萄的栽培。西北林学院学报23卷第4期江志国等宁夏酿酒葡萄气候区域化初探

Discussion on Climatic Regionalization for Wine-grape in Ningxia

Based on the climatic data(from 1996 to 2004)of reprentaticve 22 counties in Ningxia,mean temperature,extreme temperature,precipation,and insolation in different period(year,April to October,July,August,September) were studied. According to these indexes,sum of active temperature(∑T),sum of effective temperature,hydrothermal coefficient(K) and relative illumination rate(Sc) were computed.According to the sum of active temperature of growing season（from 4 to 10）,and hydrothermal coefficient(K from 8 to 9),the grapevine regions in Ningxia were divided into 3 first regions and 12 sub regions. Meteorological factors influence wine grape quality were systematically stydied. The regions suitable for culturing wine graped were in the north of Xingren,Tongxin,Weizhou,Mahuangshan in the south of these regions however, were not suitable for culturing, because of metrological limitations, such as insufficient active accumulated temperature, doughtiness, hail and frost.
