| 摘 要： | 根据华南地区１９＃抖～１９９５年的粮食气象单产和降水量资料,利用模糊数学方法评价了华南地区旱涝灾害对粮食生产的影响并计算了减产率。结果表明,夏涝和春涝对华南地区粮食生产的影响最大,所造成的减产率均占粮食气象产量的一半以上。

| Abstract: | The impact of drought based on the data set of crop yield and rainfall in South China from 1966 to 1995,and flood disasters on crop production in South China was evaluated by the method of fuzzy set theory.The reduction rate of meteorological yield was also calculated. The result shows that summer flood and spring flood have maximal impact on crop production in South China, and the reduction rates they cause are over half of the crop meteorological yield. |
