Abstract: The Qinling-huanhe Region is a transional belt in China where the typical subtropical zone changes gradually toward the warm temperate zone. There are various climatic types here. Correspondingly, the quality of rice also varies obviously with time and space and shows certain regularities. A revelation of these regularities will be helpful to causing the climate resource to transform toward the type which makes the rice quality good.

Key words: climate index of rice quality, temporal and spatial distribution of rice quality.
