摘　　要：采用基于GIS的气候资源小网格推算方法,由湖北省81个气象站的气候数据推算全省无测站区的气候要素空间分布,以县为单位对气候要素和油菜单位面积产量作相关分析,发现苗期降水量和蕾苔期平均气温与油菜单位面积产量的相关性较大,以二者为区划指标将湖北省分为三大油菜种植适宜区,得到两幅精度不同的综合气候适宜性区划图。结果表明:湖北省除西部高山地区外均适宜种植油菜,东北部和东南部为一般适宜区,中部和北部平原为最适宜区。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.
