根据对华北地区96个气象台站连续30年气候资料的分析,对华北的气候特点和葡萄适栽气候范围进行评估。对多种葡萄气候区划指标比较研究的结果表明:生长期≥10℃的活动积温,是华北地区酿酒葡萄气候区划的最适热量指标(一级指标),8～9月水热系数(K值)是适宜的二级指标。对分区标准进行适当调整后,将包括河北、山西、内蒙古及北京、天津5省(区)、市在内的整个华北地区按一级指标划分为4个气候区:冷凉区、凉温区、中温区、暖温区。每一气候区又分别按K值分为极干燥亚区、干燥亚区、湿润亚区。对各气候区的葡萄和葡萄酒生产方向和适栽品种提出建议。
According to the analysis of climatic data of 96 meteorological stations in North China for 30 consecutive years, the climatic characteristics of North China and the suitable climatic range of grapes were evaluated. The results of comparative studies on a number of grapevine regionalization indicators showed that the accumulated accumulated temperature of ≥10 ℃ during the growing season was the most suitable heat index (first-level index) for the grapevine regionalization in North China, and the hydrothermal coefficient (K value from August to September) ) Is a suitable secondary indicator. After adjusting the criteria of zoning properly, the whole North China including Hebei, Shanxi, Inner Mongolia, Beijing and Tianjin will be divided into four climatic zones according to the first-level indicators: cool area, cool area , In the temperature zone, warm zone. Each climatic zone is divided into extremely dry subzone, dry subzone and moist subzone by K value respectively. Suggestions are made on the direction of grape and wine production in each climatic zone and on suitable varieties.
