| Abstract: |
| Using the meteorological observatory data in recent 30 years (from 1981 to 2010) from 96 stations in Shaanxi Province and other stations around Shaanxi Province, included some observatory data from each county's auxiliary station and hydrological stations, based on the analysis of climatic regionalization for wine grape at home and abroad, we confirmed the indexes of climatic regionalization for wine grape in Shaanxi Province, such as the active accumulate temperature≥10℃ for the first index; the water heat coefficient at the mature period from August to September for the second index; the bury soil depth to prevent freeze injury in winter and the precipitation in September for the auxiliary index. Using the GIS technology, small gird calculation model to space the division index, and the master-slave iterative method, has made out the climatic regionalization image for wine grape in Shaanxi Province. The results showed that: In whole Shaanxi Province can be divided into 4 climatic regions and 12 climatic sub-regions. One zone from east of Xingping to the ea
st of Guanzhong, which altitude is below 900 m, is the optimal area for viticulture for wine grape. The climate factors are evaluated for each climatic region and put forward corresponding production proposals and suggestions. |
