摘 要:在对近45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软件做图,分析了气候变化引起的无霜期、初霜日、终霜日以及极限低温变化对我国酿酒葡萄栽培的影响,并对50年后我国的无霜期分布进行了预测。结果表明,近45年,特别是在20世纪80年代以后,我国的无霜期显著变长,终霜日提前,初霜日推迟,终霜日变化大于初霜日变化,埋土防寒线明显向北推移;霜冻指标变化明显受到我国阶梯形地貌的影响,在同一阶梯内霜冻指标变化影响面积大,但是在阶梯抬升地区变化更为显著;对50年后的无霜期预测表明,50年后我国北部除少数地区以外,都能够种植酿酒葡萄。Based on the analysis of climatic data from 504 weather stations nationwide in recent 45 years, the software arcgis was used to map the variation of frost free period (FFP), last frost day (LFD), first frost day (FFD) and minimum temperature. The effects of those change on Chinese viticulture zone was studied and based on the trend of FFP change rate, the distribution of FFP in future 50 years was forecasted. The results indicated that in recent 45 years especially after 1980s, the duration of FFP was increased evidently, LFD was advanced, FFD was delayed, and the bury line of-15℃ moved north, the variation of LFD was more significant than FFD; the variation of frost indexes was influenced by the step-terrain of China, in the same step, the area suffered from frost indexes change was wider, but in the area where the step rose, the change of those frost indexes were more significant. The forecast of the future FFP showed that the whole territory of north China except handful of area was suitable for grapevine growing.
