成熟期烤烟浓香型显示度气候适宜性分区研究

以国内浓香型烟叶产区8个省的28个市为研究对象,采用偏相关分析、回归分析以及模糊评价的方法,开展了气象因子与香型显示度之间的因子分析和气候适宜性分区研究。通过插值分析,描述了5个气象因子在浓香型产区的空间分布;通过偏相关分析,筛选出成熟期的30℃高温天数、日均温、20℃积温和光照时数4个关键气象因子;利用模糊评价法,划分出了3级气候适宜区,1级适宜区主要分布在豫中、豫南、皖东南、湘东南、赣南、粤北、桂东北;3级区主要分布在陕、豫、鲁3省;2级区分布于1级适宜区边缘地带。

Study on climate suitability division for the intensity of robust flavor style of flue-cured tobacco in mature stage

Taking 28 strong-flavor type tobacco producing cities in 8 provinces as the object and biased related analysis,regression analysis,and fuzzy assessment as methods,reseach was carried out on factor analysis and climate suitability division between meteorological factors and the intensity of robust flavor style.By interpolation analysis,five meteorological factors in the spatial distribution of the strongflavor type region were described.Through biased related analysis,four critical meteorological indexes were obtained as follows,the number of days with a highest temperature more than 30 °,mean daily temperature,active accumulated temperature ≥20 ℃ (AAT20),and sunlight hours during the mature period.Using the method of fuzzy assessment,meteorological suitability were divided into three levels.The first level zone is distributed mainly in southern Henan and Jiangxi Provinces,central Henan Province,southeast of Anhui and Hunan Provinces,northern Guangdong Province,and northeast of Guangxi Zhuang Autonomous Region.The third level zone is mainly distributed in Shaanxi,west of Henan and Shandong provinces.The second zone is distributed in the edge of the first zone.
