气候变化对中国酿酒葡萄气候区划的影响

The Effect of Climate Change on the Climatic Zoning for Wine Grapes in China

在对近40年全国504个气象站点气象资料进行分析整理的基础上,用Arcgis软件作图,分析了气候变化引起的无霜期、干燥度及酿酒葡萄气候区划的变化。结果表明:近40年,特别是在20世纪80年代以后,我国的无霜期显著变长,葡萄生长期增长,霜冻指标的变化明显受到我国阶梯形地貌的影响,阶梯地形显著影响不同长度无霜期的地理分布。相对于无霜期,干燥度的变化幅度不大,呈现出明显的10年期波动。近40年我国适宜酿酒葡萄栽培的面积不断向北扩大。相对于干燥度的变化,我国酿酒葡萄区域变化更多地受到无霜期变化的影响。

Based on the analysis of nationwide climatic data in recent 40 years,the software Arcgis was adopted to map the variation of frost free period（FFP）,aridity index（AI）and climatic zoning of Chinese viticulture.By the research we found that：In recent 40 years,especially after 1980s,compared to FFP,the variation of AI was not so significant,and represented a dry-moisture switch in 10 years span.The area suitable for grape-growing in China moved northwards constantly,and compared to the variation of AI,the variation of viticulturable area was much more due to the variation of FFP.
