Screening suitable areas for cigar planting and production through ecological adaptability evaluation is a prerequisite for improving the yield and quality of cigar raw materials and promoting the development of cigar industry. Taking Yishui Cigar Estate in Shandong Province as an example, using important climate indicators such as average temperature during the growth period, temperature difference between day and night, active accumulated temperature of ≥10℃ during the growth period, relative humidity during the growth period, rainfall during the growth period and average daily sunshine hours during the growth period, fuzzy clustering was carried out on 11 highquality cigar tobacco areas at home and abroad, including Havana, Binard de Río and Shifang, and the corresponding CFI values of each region were obtained through the membership function. The fuzzy clustering results showed that 11 regions could be divided into 4 categories, among which the climatic conditions of Yishui were similar to those of Havana, Pinar de Río, Dominica, Bahia, Shifang and other high-quality cigar growing areas at home and abroad, and their climate suitability index CFI values were 0.931, 0.963, 0.956, 0.944, 0.932 and 0.892, respectively, especially Yishui and Dominica’s CFI index was the most similar. It is concluded that Yishui Cigar Estate has  the ecological and climatic conditions for growing high-quality cigars.

通过生态适应性评价筛选适合雪茄烟种植生产的区域，是提升雪茄原料产量与质量、促进雪茄产业发展的前提。以山东沂水雪茄庄园为例，运用生育期平均气温、昼夜气温差、生育期≥10℃活动积温、生育期相对湿度、生育期降雨量以及生育期日均日照时数等雪茄种植生产的重要气候指标，对哈瓦那、比那尔得里奥、什邡等11个国内外优质雪茄烟区进行模糊聚类并通过隶属度函数求得各地区相应的CFI值。模糊聚类结果表明，可将11个区域划分为4类，其中沂水气候条件与哈瓦那、比那尔得里奥、什邡、多米尼加、巴伊亚州等国内外优质雪茄种植地区相似，它们的气候适宜性指数CFI值依次为沂水（0.931）、哈瓦那（0.963）、比那尔德里奥（0.956）、什邡（0.944）、多米尼加（0.932）、巴伊亚州（0.892），尤其沂水与多米尼加的CFI指数最为相近。由此得出，沂水雪茄庄园具有种植优质雪茄烟的生态气候条件。
