榆林市酿酒葡萄气候区划及种植适宜性调查研究

Investigation on Climate Regionalization and Planting Suitability of Wine Grape in Yulin City

基于文献查阅和对榆林市酿酒葡萄栽培现状的实地调查,结合榆林市各气象站点近30年的气候数据,采用小网格或空间插值方法计算榆林地区的气候特征和地理信息,并采用ArcMap软件的栅格计算器进行处理,选取无霜期和1月份平均气温作为一级气候区划的指标,将榆林市划分为适宜酿酒葡萄种植区域和不适宜种植区域。在可种植区区划的基础上,根据10℃以上的活动积温和干燥度,将榆林市划分为早熟、中熟和晚熟酿酒葡萄的种植区域,并对各区域进行了详细的区域分析。研究结果为榆林市葡萄酒产业的发展提供了相关的参考数据。

Based on literature review and field investigation of present situation of wine grape cultivation in Yulin city and combined with climate data for nearly 30 year from meteorological station in Yulin city,Yulin city was divided into suitable wine grape planting area and unsuitable area using the small grid or space interpolate methods to calculate climate characteristics and geographic information,and processing data through the ArcMap software grid calculator,and selecting the frost-free and average temperature in January as a climate zoning index.Based on planting area zoning,Yulin city was further divided into planting areas of early,medium and late ripe wine grape according to active accumulated temperature and dryness above 10℃,and a detailed regional analysis was conducted in each area.The results of the study could provide relevant reference data for development of wine grape industry in Yulin city.
