摘　　要：利用陕西省96个县(区、市)气象站及周边省份临近气象站近30a(1981—2010年)气象观测资料,辅以经订正后的各县气象哨和水文站观测数据,在对国内外葡萄区划指标分析基础上,确定以≥10℃活动积温为一级指标,酿酒葡萄成熟期8—9月水热系数为二级指标,冬季埋土防寒线、9月降水为辅助指标作为陕西省酿酒葡萄气候区划指标。基于GIS技术,利用小网格推算模型对区划指标空间化后,采用主从叠代方法,制作陕西省酿酒葡萄气候区划图。结果表明,陕西省酿酒葡萄种植可分为4个气候区和12个气候亚区,自兴平以东的关中东部海拔900m以下地区是陕西省种植酿酒葡萄的最优区;对各区酿酒葡萄生产的气候因子进行了评价,提出了相应的生产建议。Using the meteorological observatory data in recent 30 years （from 1981 to 2010 ） from 96 stations in Shaanxi Province and other stations around Shaanxi Province ,included some observatory data from each county’s auxil-iary station and hydrological stations ,based on the analysis of climatic regionalization for wine grape at home and abroad , we confirmed the indexes of climatic regionalization for wine grape in Shaanxi Province ,such as the active accumulate temperature≥10℃ for the first index ;the water heat coefficient at the mature period from August to September for the second index ;the bury soil depth to prevent freeze injury in winter and the precipitation in September for the auxiliary in-dex .Using the GIS technology ,small gird calculation model to space the division index ,and the master-slave iterative method ,has made out the climatic regionalization image for wine grape in Shaanxi Province .The results showed that ：In whole Shaanxi Province can be divided into 4 climatic regions and 12 climatic sub-regions .One zone from east of Xing-ping to the east of Guanzhong ,which altitude is below 900 m ,is the optimal area for viticulture for wine grape .The cli-mate factors are evaluated for each climatic region and put forward corresponding production proposals and suggestions .
