摘要
[目的]研究云南烟区6个气候要素的聚类。[方法]采用系统聚类分析对云南植烟区12个地州89个植烟县的6个气象要素进行聚类分析,根据各类型的指标特征及气候特点,对云南省主要植烟区的气候进行划分。[结果]云南省主要植烟区的气候可划分为8个类型,分别是以江川(24个县,属北亚热和中亚热气候带)、嵩明(27个县区,属北亚热和中、南、北温气候带)、腾冲(3个县,属北亚热气候带)、弥勒(12个县,属中亚热和南亚热气候带)、邱北(11个县区,属南亚热气候带)、盐津(4个县,属中亚热带湿润气候带)、元江(4个县,属南亚热和北热气候带)、镇雄(3个县,属暖温带和北亚热气候带)为代表。第1～8生态区气候达1级相似的国内外城市分别有3、1、1、0、1、1、0、1个市,达2级相似的分别有12、15、3、13、13、1、5、3个市。8大生态区中,1级相似的城市相似距离在0.28～0.45,相似程度最高,相互引种容易成功;2级相似的城市相似距离在0.51～1.00,相似程度较高,相互引种成功率较高。[结论]该研究为选择适宜不同地区种植的新、引烤烟品种以及优化不同地区烤烟品种布局提供理论依据。
[Objective] The research aimed to study clusters of the six climatic factors in Yunnan tobacco planting zone.[Method] 6 meteorological elements in 89 tobacco-growing counties and 12 prefectures were conducted cluster analysis.According to indicator and climate characteristics of the each type,climate in tobacco planting area of Yunnan Province was divided.[Result] Climate could be divided into eight types： Jiangchuan（24 counties,belonged to northern and central subtropical climates）,Songming（27 counties,belonged to northern subtropical and central,southern,northern warm climates）,Tengchong（3 counties,belonged to northern subtropical climate）,Mile（12 counties,belonged to central and south subtropical climates）,Qiubei（11 counties,belonged to south subtropical climate）,Yanjin（4 counties,belonged to central subtropical humid climate）,Yuanjiang（4 counties,belonged to southern subtropical and north tropical climates）,Zhenxiong（3 counties,belonged to warm and northern subtropical climates） as the representative.Among 1-8 eco-zones,domestic and foreign cities that climate reached one-level similarity were respectively 3,1,1,0,1,1,0 and 1,up to two-level similar,respectively 12,15,3,13,13,1,5 and 3.Among 8 major ecological zones,similar distance of the one-level similarity city was in the range of 0.28 to 0.45,and similar degree was the highest.Variety introduction between these places would be successful.Similar distance of the two-level similarity city was between 0.51 and 1.00,and similar degree was higher.Mutual variety introduction had high success rate in these places.[Conclusion] The research provided theoretical basis for selecting new suitable tobacco variety and optimizing tobacco variety layout in different zones.
