| 中文摘要: |
| 以川西高原及周边地区73个气象站点1982-2011年30 a的逐日气象数据和川西高原90 m DEM数据为基础，选用生长季活动积温为酿酒葡萄气候区划的热量指标，干燥度为水分指标，采用多元逐步回归法分别建立了生长季活动积温和干燥度与地理、地形因子的关系模型，再结合残差内插法得到了空间化的气象数据模拟值，绘制了川西地区酿酒葡萄适宜栽培区分布图。研究结果显示，川西高原葡萄适宜栽培区分布在白水江河谷，岷江河谷，麻尔柯河及梭磨河河谷，多柯河河谷及大金川河谷，大金川及其支流河谷，雅砻江及其支流鲜水河河谷，水洛河河谷，金沙江及其支流硕曲、定曲河谷及大渡河河谷部分地区，与川西高原干旱河谷的分布一致；本区西南部酿酒葡萄适宜栽培区在海拔3 000 m以下，东北部大致在海拔1 300~2 500 m之间，东南部一般在1 700~2 800 m之间，不同区域、不同熟性葡萄适宜栽培的海拔范围有较大差异。将葡萄栽培区分布与区划结果对比发现，现有的葡萄实际栽培区全部分布在区划图中的葡萄适宜栽培区内，此区划方法适用于川西高原地区。 |

| 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. |
