Abstract: On the basis of summarizing all of main index systems of viticultural climatic zoning in China, all of current internal index systems of grapevine climatic cultivation are compared and analyzed from the climatic background, climatic zoning areas, means, and results. It deems that the major external indexes in grapevine cultivation, hydrothermal coefficient, accumulated temperature, level division-temperature index, heliothermal index, hypothermal coefficient ,etc, referred by internal experts are not suitable for all zoning of China. It also believes that only when establishing the new index system which has considered Chinese own geography and climate, the other analysis methods could embody their potential. It still reckons that the new cultivation system (frost-free period, dryness index, and bury line), founded by Li Hua et al is the first one regarding Chinese own climate features at present. Moreover, there are three problems: Firstly, the choice of indexes could not consider Chinese climate; Secondly, all the climatic zoning of viticulture are always from one theory to another theory, never go deep into the practice in order to verify their reliability; Thirdly, there is never a integral viticulture zoning which not only reaches entire country, but also goes into details on every areas. While the problems existing in the climatic zoning system for viticulture are indicated, the development trend of grapevine climatic zoning in China is also predicted. At last, some suggestions on climatic zoning in China are proposed. Based on the comparative analysis, a theoretical foundation of improvement and unity of indexes system of viticulture zoning in China is provided.
