摘　　要：利用GIS和模糊集建模技术,通过采集和检测四川烟区土壤和烟叶样品,收集整理四川气候和地形地貌资料,对烟叶质量与生态条件的相关性进行分析,确定评价因子,并进行生态适宜性评价。结果发现,海拔高度、日照时数和土壤类型可以作为四川烤烟生态适宜性评价的关键因子。全省9.52%的土地面积为烤烟最适宜区;烟区39.89%的面积为最适宜区,24.20%的面积为适宜区。现存烟区按地理位置划分为3个大区,各区按生态适宜性评价结果再细分为最适宜、适宜、较适宜和不适宜区。A series of assessments on ecological adaptability of flue-cured tobacco in Sichuan Province were conducted by usingGIS and fuzzy set in order to properly identify the best planting regions and improve raw material supply to cigarette industry. Thesoil and tobacco leaf samples from tobacco planting regions in Sichuan were collected and tested, and local climatic and terrain datawere collected as well. The assessment factors were identified by correlation analysis between tobacco leaf quality and ecologicalparameters, and ecological assessment was carried out. The results showed that altitude, sunshine hours, and soil type could be usedin assessing the adaptability of tobacco in Sichuan. Nine point five two percent of the land area in Sichuan Province was in thecategory o f ‘Ihe most suitable for tobacco production” and 39.89% of existing tobacco production areas were in the “most suitable”and 24.20% were in the ^suitable5＇ categories, respectively. The existing tobacco production areas could be classified into 3 primaryzones, which could be further classified as the most suitable, suitable, less suitable, and not suitable zones.
