摘　　要：为掌握安徽省宣城地区双季早稻种植气候适宜性地域分布,通过宣城地区7个国家气象观测站1981-2010年温度、降水、日照数据和地理信息数据,应用模糊数学方法和空间插值方法对宣城地区温度、降水、日照和气候适宜度进行了研究。结果表明,该地区温度和日照适宜度较高,降水适宜度较低,降水是影响该地区双季早稻种植的主要不利因子,温度的不利影响主要表现在双季早稻生产前期。根据综合气候适宜度分析,适合双季早稻种植气候区主要集中于宣城北部平原地区。In order to understand climate suitability of double early rice in Xuancheng area, based on geographic information and ob-servational data of seven meteorological stations from 1981 to 2010, and by using fuzzy mathematics and spatial interpolation methods, the climate suitability of double early rice in this area were studied. The results showed that the temperature climate suitability was higer than others; precipitation suitability was at lower lever, precipitation and sunlight suitability were the unfavorable climate factors affecting the growth of double early rice, the bad effec of temperaturet on double early rice is in the early period of production. By the analysis of compositive climate suitability, the best planting areas for double early rice mainly focus on northern plateau.
