摘要： Hexi Corridor is one of the most important wine grape cultivation areas in China and local wine industry is developing rapidly. The detailed study on regionalization of wine grape varieties may provide the scientific basis for the selection of wine grape varieties. In the study, according to the climatic characteristics in Hexi Corridor, with the two regionalization indicators of the frost-free period and active cumulative temperature, the areas with the frost-free period longer than 150 days and the active cumulative temperature higher than 2500 degrees C were classified as the suitable cultivation areas of wine grape. With the average meteorological data of 46 meteorological stations surrounding Hexi Corridor from 1980 to 2010 and the 90-m DEM data of Hexi Corridor, the models of the frost-free period and the cumulative temperature were established according to the multivariate stepwise regression method. In addition, the regionalization diagram of the wine grape varieties in Hexi Corridor was plotted with the residual interpolation method. In the diagram, the optimum wine grape cultivation region was divided in six areas according to active cumulative temperature and suitable wine grape varieties and proper cultivation elevation ranges were proposed for corresponding areas. The existing data of the grape quality in different wine grape cultivation areas in Hexi Corridor supported the regionalization results. The study results provided a theoretical basis for the selection of wine grape varieties in Hexi Corridor.
