河西走廊酿酒葡萄生态气候资源定量分析及评价

Quantitative Analysis and Evaluation on Eco-climatic Rescoures of Winemaking Grapes in Hexi Corridor

运用2002—2003年试验观测资料,在筛选影响酿酒葡萄生育主要气象因子的基础上,建立了各因子适宜度隶属函数和酿酒葡萄气候适宜度动态模型,计算了河西地区酿酒葡萄各种生态气候指数,用多年酿酒葡萄不同生育阶段平均效能指数的模糊聚类,将河西划分为4种生态气候资源类型并进行了分类评价,为酿酒葡萄种区域化和不同生育阶段生产管理提供了理论依据。

Based on the observed data from 2002 to 2003 of main screened meteorological factors which influence on the growth of winemaking grapes in the Hexi corridor, we have established the function of each factor＇s suitability and the dynamic model of climatic suitability for winemaking grapes; have calculated the eco-climatic index of winemaking grapes in every county of Hexi district; have sorted the four eco-climatic resource types by using the fuzzy cluster on average efficiency index of winemaking grapes at different growth stages, additionally have evaluated the every eco-climatic resource type. The study can provide theoretical foundation for the regionalization of winemaking grapes and their management at each growth stages.
