摘　　要：通过对甘肃省一般气象站点20年的气候资料进行统计分析,按照李华等提出的气候区划指标体系,即采用无霜期作为一级指标,干燥度作为二级指标,埋土防寒线作为三级指标,将甘肃省划分为9个气候区。确定了河西走廊地区、白银中部地区、兰州周边县区为酿酒葡萄的最佳产区,其余地区为一般适宜区,可发展适应性较强的酿酒葡萄品种,还有某些特殊的小气候区域也能生产优质或优良葡萄与葡萄酒,但需进一步研究细化。通过对光热指数、纬度-温度指数、有效积温3个品种区划指标的计算分析,结合甘肃省目前酿酒葡萄实际的种植情况,确定了光热指数比较适合作为甘肃省酿酒葡萄品种区划的指标,并根据计算结果提出了每个区域适合栽种的酿酒葡萄品种。Gansu Province is subdivided into 9 climate areas in this paper, based on the climatic zoning system proposed by Li Hua, et al, according to the climatic data of general weather stations in Gansu Province during 20 years. In the climatic zoning system, the frost-free period is used as the first index, the dryness index as the second index, and the level of earth burial to keep warm as the third index. Hexi Corridor, the center area of the Baiyin and the countryside of Lanzhou are shown to be the most suitable viticulture zones. Other areas see some unfavorable conditions such as overabundance of moisture in harvest-time, hence, are defined as the ordinary viticulture areas. In other special areas or small areas, high quality wine production also can be expected, a further subdivision is needed. By the comparison of three grapevine variety zoning indexes： Index of Huglin （IH）, LTI and the effective active accumulated temperature, considering the actual situation of the viticulture in Gansu Province, the IH in grape growing season is found to be appropriate for variety zoning. And the suitable viticulture varieties are determined for each area through the results.
