Abstract: The spatial distribution of climate factors without-station in Hubei province was calculated based on the data from 81 meteorological stations by using the method of GIS-based small grids reckoning of climate resources.Then the relationship between climate elements and rape yield in each county was studied.The results showed that rape yield had significant correlation with precipitation at seeding stage and average temperature at peduncle-growing period.Three suitable regions for rape planting were divided in Hubei province according the result.So rape could be planted in Hubei province apart from west mountain region.The northeast and southeast were general suitable regions,while the central and northern plains were the most suitable regions.
