Evolution and prediction of climate suitability for flue-cured tobacco cultivation in Southwest China based on CMIP6 climate model
[Objective]The effect of future climate change on climate suitability of tobacco cultivation is explored to provide a reference basis for optimizing the spatial layout of tobacco cultivation in Southwest China.[Method]The spatial and temporal changes in future zoning of cli-mate suitability for tobacco cultivation in Southwest China were analyzed by Hierarchical analysis and inverse distance interpolation based on the single-pattern climate predicted data of CMIP6.[Result]The climate suitability of tobacco cultivation in Southwest China would be domi-nated by medium-suitable zone(area proportion＞28％ ),followed by high-suitable zone and low-suitable zone with a smaller area of unsuita-ble zones under the future climate change.The area and proportion of high-suitable zone and low-suitable zones would increase more promi-nently but the area and proportion of medium-suitable zone and unsuitable zone would decrease significantly.The area and proportion of high-suitable zone and low-suitable zone both would be on the rise in most of the future and the area and proportion of medium suitable area and unsuitable area both showed a decreasing trend compared with the data during 1970-2000.[Conclusion]The climate suitability of tobacco cultivation shows an overall increasing trend but there is the significant spatial heterogeneity in climate suitability of tobacco cultivation among different periods in Southwest China.
