摘　　要：根据内江市农业农村局2010—2015年的数据统计,基于气象灾害分类和粮食作物类型,采用灰色关联模型,从灾害范围和灾害强度2个方面分析气象灾害对粮食生产的影响。研究结果表明:(1)气象灾害严重影响了内江市的粮食生产量。其中旱灾对内江市粮食生产具有重大影响。(2)粮食生产与四大气象灾害的相关性采用灰色关联分析得到:干旱>冰雹>洪涝>霜冻,其是水稻、小麦、玉米、大豆和薯类作物产量的主要影响灾害。According to the data statistics of Neijiang Agriculture Bureau from 2010 to 2015, based on the classification of meteorological disasters and types of food crops, the grey correlation model was adopted to analyze the impact of meteorological disasters on food production from two aspects of disaster scope and disaster intensity.The results showed that :(1) meteorological disasters seriously affected the grain production in neijiang city. The drought had a significant impact on neijiang grain production.(2) Grey correlation analysis was used to analyze the correlation between grain production and four major meteorological disasters: drought > hail > flood > frost, which was the main disaster affecting the output of rice, wheat, corn, soybean and potato crops.
