摘要
为实现基于烟叶品质的云南烤烟种植气候精细化分区。在烤烟种植气候适宜性分区基础上,应用GIS技术、系统聚类和灰关联度分析方法,研究云南烤烟化学品质类型的气候分区。结果表明,云南气候可出产4类化学品质特点鲜明的烟叶,并主要适产"中高糖中低氮(碱)中低石油醚提取物"、"高糖低氮(碱)低石油醚提取物"两类品质烟叶;前者盛产于滇中的烤烟气候最适宜和适宜区,后者多产自滇西南大部的烤烟气候次适宜区和适宜区。两种分区结果既有一致性和客观性,也存在显著差异,但不相互矛盾。两种分区的有机结合应用,可加深关于云南烤烟气候及其对烟叶品质影响的认识,提高云南烤烟种植气候区划的科学性和生产实用指导性。
On basis of the existed climatic suitability division of the flue-cured tobacco planting, the division of the tobacco-leaf quality was made, by using GIS techniques, hierarchical clustering and grey correlative analysis. The resuits showed that four different chemical quality types of tobacco leaf were produced under the climate conditions in Yunnan, especially favorable to the mid-high sugar and low nitrogen or nicotine mid-low petroleum ether extract （type Ⅰ ） , and high sugar and low nitrogen or nicotine thin petroleum ether extract （type Ⅱ）. The moist suitable and suitable regions for type I were in the middle Yunnan, while the less suitable and suitable regions were in the southwest Yunnan. The results for division of the suitable regions and of the tobacco leaf quality were consistent in some extents and complementary to each other.
