以我国四个主要产区贺兰山东麓产区、河西走廊产区、怀涿盆地产区和通化产区国产葡萄酒为样本，采用电感耦合等离子体质谱法测定铜含量，分析我国国产葡萄酒中铜含量状况。结果表明我国葡萄酒中铜含量状况整体良好，铜超标检出率为0.2%。在四个产区中，通化产区葡萄酒铜含量最高，其次为贺兰山东麓产区，河西走廊产区和怀涿盆地产区较低。通化产区葡萄酒中铜含量呈两极化分布，贺兰山东麓产区样品铜含量则集中分布在50~100 μg/L和100~300 μg/L两个区段，而河西走廊与怀涿盆地两个产区的铜含量分布较为平均。分析显示，气候风土特征、酒庄葡萄园管理手段与酿造技术对葡萄酒中的铜含量的影响很大。葡萄品种在同一产区不同酒庄中的表现是类似的，但受产地风土与气候条件影响，在不同产地表现又有一定的区别。年份对于铜含量也有一定的影响，主要与当年的气候尤其是降水情况相关。

The copper contents of wines from Helan Mountain East region, Hexi Corridor region, Huaizhuo Basin region, and Tonghua region were investigated using inductively coupled plasma-mass spectrometry (ICP-MS). Results showed that the copper content of wines obtained from these four regions was in a good condition overall; the detection rate of excess copper content was 0.2%. Among the four regions, Tonghua region showed the highest copper content, followed by Helan Mountain East region, while Hexi Corridor region and Huaizhuo Basin region showed relatively lower copper contents. The distribution of the copper content in Tonghua wine was polarized. The copper content in the Helan Mountain East region ranged between 50~100 μg/L and 100~300 μg/L, while the Hexi Corridor region and Huaizhuo Basin region showed a more uniform distribution of copper content. Regional climate and terroir characteristics, winery and vineyard management, and winemaking technology exert large effects on the copper content of wines. The copper contents of different wine grape varieties in the same region were similar, but there were certain differences between the wine grape varieties of different regions. Vintage also had a certain influence on copper content, which was mainly related to the climate, especially to precipitation.
