基于1971-2010年湖南省97个站地面气象观测资料，利用空间插值等GIS技术，选取8℃～22℃活动积温和3月下旬-10月日照时数为区划指标，进行湖南超级双季稻熟性搭配精细化气候区划，并通过不同年代段的动态气候区划比较，分析了气候变化对湖南双季超级稻种植适宜性的影响。结果表明，湖南适宜种植双季超级稻的区域面积大，“迟熟+迟熟”区主要位于湘南的平原地区；相对于1971-2000年，1981-2010年湖南双季超级稻“迟熟+迟熟”区、“中熟+迟熟”区面积明显增加，同时向北扩展；“中熟+中熟”区、“早熟+早熟”区面积有所减小；“早熟+中熟”区面积变化不大；不适宜区面积略有增加。建议在稳定现有种植面积的同时，在湘江流域和洞庭湖区采取一定的激励措施，扩大双季超级稻种植面积。

Based on meteorological data from 97 stations in Hunan Province during 1981-2010 ,the refined climatic regionalization of double cropping super rice maturity in Hunan Province was studied by using spatial interpolation and other GIS technologies, and se-lecting active cumulative temperature of 8~22℃ and sunshine hours from late March to October as the index of regionalization. By comparing dynamic climate regionalization of different decadal periods, the paper analyzed the influence of climate change on double cropping super rice planting adaptability. The results showed that the suitable planting area of double cropping super rice in Hunan was very large, the area of late maturing(of early rice) with late maturing(of late rice) was mainly located in southern plains of Hu-nan. Relative to 1971-2000, the area of late maturing with late maturing, medium maturity with late maturing increased significantly, and expanded northward; the area of medium maturing with medium maturing and early maturing with early-maturing decreased; the area of medium maturing with early maturing changed little; the unsuitable area increased. It is recommended to stabilize the existing acreage and take certain incentives to expand the planting area of double cropping super rice in Xiangjiang River Basin and Dongting Lake district at the same time.
