山东省酿酒葡萄气候区划

 采用中国气象中心提供的山东省123个气象站点连续30年（1979—2008）的气候资料，排除不能种植酿酒葡萄和数值缺失较多的3个站点，对余下的120个站点气象资料进行分析。采用李华等提出的指标体系，即利用无霜期作为第一指标、生长季干燥度为第二指标、埋土防寒线为第三指标。结果显示，在山东省，生长季干燥度能很好地判断一个地区能否种植葡萄，但对适宜种植产区的优劣区分得不好，因此应根据实际情况选择第四个指标，通过分析山东省的气候特点（雨热同季），排除水热系数，采用成熟季（7—9月）降水量作为第四指标。利用这4个指标对山东省进行酿酒葡萄气候区划，通过Excel软件对区划指标进行计算分析，根据计算结果利用ArcGIS软件作图。将山东省划分为2个优质区，1个优良区，3个一般产区和1个可种植区，初步评价了各区适合种植的品种种类。

Climatic Zoning of Grapevine in Shandong Province

The climatic data of 120 meteorological stations in Shandong Province(provided by China Meteorological Administration) for 30 years (1979—2008) are used in this study, excluding three stations whose data are lost or which are not suitable to plant grapes. Based on the climate data of 120 meteorological stations, Shandong Province can be classified by using the zoning indexes proposed by Lihua et al. with the number of frost free days as the first index, the dryness index (DI, from April to September) as the secondary index and the mean lowest temperature below -15℃ as the tertiary index. The results show that the DI in the growing period (from April to September) is a good index in judging whether an area is suitable for vine cultivation, but is not a good index in estimating how good the area is for vine cultivation. So in this paper, the precipitation in the mature season (from July to September) is chosen as the fourth index. These indices are handled by Excel software and are plotted by ArcGIS software. By applying this zoning system, Shandong Province is divided into 7 cultivated zones, with one that can produce the highest quality grapes, one for high quality grapes, 3 zones for general quality grapes and one zone that can only produce wine. An evaluation on the varieties adopted in every zone is made and it is concluded that Shandong Province is suitable to grow late-harvested or surplus mature grape varieties.
