摘　　要：利用湖北省76个气象站1981-2010年气候资料和1∶100万DEM数字高程模型,采用回归克里金插值法分别对稳定通过10℃活动积温、水稻生长期长度、安全生育期天数等区划指标进行了细网格推算,综合考虑区划指标等级评分对湖北省水稻种植布局进行了精细区划。区划结果显示湖北省除局部高山地区外,大部分地区热量条件可满足一季中稻种植,三峡河谷、鄂西南东部低山丘陵区、江汉平原及鄂东沿江平原可种植一季早熟籼稻和一季早中熟晚籼稻,与当前实际种植范围相比,双季稻的种植北界尚有北移的空间,考虑早籼+晚粳以及单季稻改双季稻的种植模式,双季稻的种植范围仍具有较大的扩展潜力。区划结果对湖北省水稻种植规划及布局调整具有重要指导意义。Based on the daily meteorological records of 76 stations from 1981 to 2010 and 1 ∶100 digital elevation model（DEM） of Hubei province,three key indices including accumulated temperature of not less than 10 ℃,length of growing season suitable for rice cropping and safe period for heading,were calculated and downscaled to grids of 1 km×1 km with regression-kriging models,and then maps of fine climatic regionalization of rice cultivated patterns were generated. The results showed that the heat conditions in most parts of Hubei province could meet the climatic requirements of one season rice growth and development,except for the high altitude area in the west,and the heat conditions in three gorges valley,low mountains and hills in southwest Hubei,Jianghan plain and plain along yangtze river in east Hubei, were sufficient for double season rice cropping.Compared with the current cultivation area,the northern limits of double season rice cropping system moved northwards,and the cultivated areas of single season rice had great potential for double season rice cropping,considering changing the varieties of late season rice from indica to japonica type,there was large potential for the expanding of double season rice.The results could provide reference for rice cultivation plan and adjustment.
