摘　　要：【目的】‘玫瑰蜜’葡萄是我国大香格里拉河谷区广泛栽培的酿酒和鲜食兼用品种,系统比较了不同海拔‘玫瑰蜜’葡萄园微气候的差异与‘玫瑰蜜’品质形成的关系。【方法】采用方差分析方法、PLS-DA和多项式数值模拟法,分析了‘玫瑰蜜’品质在不同海拔区域的差异及与气象因子的关系。【结果】海拔差异对‘玫瑰蜜’果实品质有显著影响,种植于香格里拉河谷区海拔1 860-2 102 m的区域内品质较好,而种植于高海拔2 797 m和低海拔1 117 m葡萄园中的品质较差,不同海拔‘玫瑰蜜’葡萄的温度、光辐射强度、水分状态与‘玫瑰蜜’葡萄果实的糖分、酸度、可溶蛋白质、多酚含量密切相关。【结论】‘玫瑰蜜’葡萄品质的优劣与栽培区域的气象因子密切相关,香格里拉干冷河谷区海拔1 860 m和2 102 m的区域更适合优质玫瑰蜜葡萄的生产。【Objective】‘Rose Honey ＇（Vitis vinifera-V. labrusca） was identified as a hybrid species byV. vinifera and V. labrusca, it provides special grape varieties for table wines which have been cultivatedin the Widely Shangri-La Valley within high altitude regions, including the Yunnan plateau region of Deq-in County.‘Rose Honey＇grapes have been cultivated in Cizhong since 1848 by French missionaries whenthe grapes became extinct in their original region of French. it is therefore necessary to provide more agri-cultural information on the Shangri- La Valleys＇ ‘Rose Honey＇grapes, to better understand the‘RoseHoney＇berry＇s genesis in the Shangri-La Valley. It is also necessary to explore the relationship betweenthe different altitudes＇ effect on the‘Rose Honey＇vineyard＇s microclimate and berry composition accumu-lation, and finally, to understanding the theoretical basis for producing the high-quality‘Rose Honey＇grape and brewing the high-quality wines in the Shangri-La Valley.【Methods】Experiment sites： altitudesof 1 117 m, 1 860 m, 2 102 m, and 2 797 m representing Xichang, Cizhong, Buncun, Hongpo respectively;these four different altitude gradient vineyards＇ used 40 plants of the‘Rose Honey＇grapes for the experi-ments. Meteorological data collected： Meteorological data of 1 117 m, 1 860 m, 2 102 m, and 2 797 m alti-tude gradient vineyards were collected by using the GPRS-Base system, along with continuous monitoringof the climate parameters such as solar radiation, temperature, daylong, rainfall and relative humidity; thedata was recorded each 15 minutes during the years, 2013 and 2014. Sample collection and preparation：samples consisted of randomly collected grapes from the various vineyards. Samples were stored at 4 ℃for transportation and laboratory analysis. Samples were crushed using a winepress, 1 349 centrifugalgrams for 10 minutes, then the filtration fluid was carefully collected and stored at-20 ℃ for the‘RoseHoney＇berry composition test, soluble
