Abstract:Based on the analysis of nationwide climatic data in recent 45 years, the software ArcGIS is used to map the variation of Frost Free Period (FFP), Last Frost Day (LFD), First Frost Day (FFD) and minimum temperature. Their effects on viticulture zoning in China are studied. Based on the trend of FFP variation rate, the distribution of FFP in 50 years is predicted. It is found that in recent 45 years, especially after the 80s of the last century, the duration of FFP is increased, LFD is advanced, FFD is delayed, and the bury line of -15℃ is moved northward, the variation of LFD is more significant than FFD; the variation of frost indexes is influenced by the step-terrain of China, the area affected by frost indexes change is wide in a same step, but in the areas with a higher step, the variation of those frost indexes is more significant. The prediction of the future shows that the whole territory of north China is suitable for grapevine growing, except some small areas.
