Abstract:

Observation data of about 40 meteorological stations in the central and southern Jiangxi Province from 1959 to 2018 were used to explore the risk division of the meteorological disasters for tobacco planting, based on the analytic hierarchy process (AHP) method and the fuzzy comprehensive evaluation method. In order to get an accurate and elaborate division, the spatial analysis function of ArcGIS was adopted and the full growth period indicators of tobacco were taken into the study. The results showed that: in the weight order, the major meteorological disasters affecting tobacco planting in the central and southern Jiangxi were rainstorm, hail, continuous rainfall, low temperature freezing and heat injury, among which, rainstorm risk was higher in the east than that of in the west, and the risk of hail was higher in the northwest than that in the southeast, and the risk of continuous rain was higher in the west than that in the east with a decreasing trend from north to south, besides the risk of low-temperature freezing disaster and heat injury was higher in the north than the south, and was evenly distributed from east to west. Generally speaking, the comprehensive risk of meteorological disasters in tobacco planting areas in Jiangxi is distributed high in the north and low in the south, and the high-risk areas of comprehensive meteorological disasters are mainly distributed in the northern areas of Fuzhou and Ji'an. The results could minimize the impact of meteorological disasters on tobacco production in Jiangxi.
