摘　　要：江西省瑞金市被全国第二次烤烟种植区划综合评定为烤烟生产最适宜区,烟叶产业发展已规划为当地农民致富、财政增收的重要项目,是瑞金市以农业产业结构调整为主导的新农村建设的重要内容,寻找适宜的植烟土壤是科学布置烟草生产的基础。本研究在GIS的支持下,利用层次分析和特尔菲等评价方法,从土壤养分性状、立地条件、土壤管理三个层次确定瑞金市耕地植烟适宜性评价的评价指标及权重,构建适宜性评价模型,对瑞金市耕地的植烟适宜性进行评价,将瑞金市耕地划分成四个等级适宜区域:S(I)耕地5143.83公项、S(II)7262.07公项、S(III)6540.38公项、S(IV)2241.1公顷,分别占耕地总面积的24.28%、34.27%、30.87%和10.58%。The development of tobacco industry is planned as an important project for making farmer richness and financial income increased and as a main task for new countryside construction in Ruijin, Jiangxi Province. This area is the most suitable for planting tobacco based on the comprehensive assessment of the second national planting tobacco regionalization. Suitability soil is the basis of tobacco production. Soil nutrient characteristics, site conditions,and soil management were chosen as the basic evaluation indices. A geographic information system(GIS), combined with AHP and Delphi, was used to weight the evaluation index, construct the suitable model, and evaluate the soil suitability for planting tobacco. The cultivated land was divided into four grades areas of suitable planting tobacco: S(I) 5143.83 ha, S( II) 7262.07 ha, S( III) 6540.38 ha, S( IV) 2241.1 ha, accounting for 24.28%, 34.27%, 30.87%and 10.58% of the total cultivated land in Ruijin, respectively.
