Abstract: In order to explore the meteorological disaster risk of tobacco under complex terrain in Fujian province, and to avoid or reduce loss, the risk system of impacts of multi-disasters on tobacco, including hazard of disaster-causing factors, vulnerability of tobacco and disaster prevention and mitigation capabilities of tobacco regions, was established in this paper, based on the meteorological data from 1972 to 2008 in 28 tobacco planting areas, planting area and yield of tobacco from 2008 to 2013, and other socio-economic data. Then the indicator weight was determined, the comprehensive risk was calculated, and risk division was given, by methods such as analytic hierarchy process, entropy-weight coefficient method, weighting method, and GIS. The results showed that the comprehensive risk of meteorological disasters in the regions of tobacco in Fujian increased step by step from southeast to northwest. The regions of mild comprehensive meteorological disaster risk were mainly distributed in the mid-east of Longyan city, east of Sanming city and some areas of eastern Nanping city. The moderate risk regions were mainly distributed in west of Longyan and the region between east and west of Nanping and Sanming. The severe and more severe risk regions were mainly distributed in the northwest mountainous areas of Nanping and Sanming, among then, the areas where the attitude higher than 1000 meters had more severe risk of meteorological disasters.
