基于耕地地力评价成果，采用层次分析和GIS技术对两当县烤烟种植适宜性分布区域进行了研究。结果表明:两当县适宜种植烤烟的土地面积为10 843.16 hm2，占全县耕地面积的55.66%；主要分布在金洞乡、鱼池乡、站儿巷镇、显龙乡、兴化乡等地；不适宜种植区的主要影响因素为降水量较大、海拔高、气候冷凉等。并提出两当县烤烟产业的发展建议是:改良土壤，提高烟叶的可用性；烟叶种植区域和品种要服从于烟叶的可用性。

Based on the results of the evaluation of cultivated land fertility， using AHP and GIS technology of Liangdang County tobacco planting suitability distribution area are studied. The result shows that Liangdang County for tobacco area of 10 843.16 hm2， 55.66% of the total arable land；mainly located in Jindong， Yuchi， Zhaner， Xianlong， Xinghua township； not suitable for the main influencing factors of the main planting areas for greater rainfall， altitude， cold climate etc.. And put forward the development proposal of Liangdong county flue-cured tobacco industry is improve the soil， improve the usability of tobacco leaves； tobacco planting areas and cultivars should obey the usability of tobacco leaves.
