Abstract: Based on comprehensive analysis in flue-cured tobacco relationship with climate,using the 10 meteorological stations statistical data from 1981 to 2010, To establish the Flue-cured tobacco suitability evaluation Meteorological factor and the space of the geographic information system mode,with 3 s (GIS, RS, GPS) technology as support,integrated The key factors such as longitude, latitude, altitude, gradient, slope direction, precipitation, sunshine, temperature and so on high precision for study on flue-cured tobacco suitability division in chuxiong, Results show that:the state of most suitable flue-cured tobacco planting area is 60.74% of the total area,the suitable for planting flue-cured tobacco area is 24.14% of the total area,the secondary suitable planting area accounts is 8.96% of the total area,the not suitable for planting area accounts is 6.14% of the total area,Identify the geographical position of suitable planting flue-cured tobacco or not,And its reason was analyzed,For the next planting flue-cured tobacco, reasonable planning of modern tobacco agriculture provide the reference,At the same time also for the majority of agricultural regionalization researchers provides a new method of high precision small grid of agricultural regionalization
