| Abstract: |
| This study was performed based on the daily meteorological data of last 30 years (1982-2011) and 90 meter Digital Elevation Database (DEM) of 73 meteorological stations in the Western Sichuan Plateau and its surrounding areas to build a suitable cultivation area map for wine grape growth. We used the active accumulated temperature in growing season of wine grape as the heat index and the dryness index as the moisture index for the climatic regionalization for wine grape growth. The relationship between active accumulated temperature and dryness in growing season and the geographical and topographical factors were modeled using the multiple stepwise regression method. In combination with the residual interpolation method, the spatialization simulation values were obtained. Then, a cultivation suitability distribution map for wine grape growth in the Western Sichuan was developed. The suitable areas are mainly distributed in Baishui River valley, Minjiang River valley, Maerke River valley, and Suomo River, Duoke River valley, Dajinchuan River and its tributary valley, Yalongjiang River and its tributary valley, Shuiluohe River valley, Jinshajiang River and its tributary valley, Dadu River and its tributary valley. The suitable cultivation elevation of wine grape was approximately 1 300~2 500 m in northeastern part, approximately 1 700~2 800 m in southeastern region, and below 3 000 m in the southwestern region of the study area. The result showed that all of the suitable cultivation area for wine grape in the Western Sichuan Plateau distributed in the dry valleys, but the elevation varied significantly among regions and also grape varieties. The comparison of the current the grape cultivation area and the climatic regionalization results in this study indicated that the current growth of wine grape are all distributed in the suitable cultivation area. Therefore, this distribution map can be used for guiding wine grape growth in the Western Sichuan Plateau. |
