利用江苏省 1 949～ 1 992年的粮食产量、气象资料 ,分析了粮食单产和粮食播种面积对总产年际变化的影响以及技术水平因素、社会因素和气象因素 (尤其是气象因素 )分别对粮食单产年际变化的影响。结果表明 :引起江苏省粮食产量波动的主要原因是气象条件。在此基础上 ,从减轻气象灾害的角度分析了江苏省的粮食生产 ,并提出了相应措施。
Using the grain yield and meteorological data from 1949 to 1992 in Jiangsu Province, the effects of grain yield per unit area and grain sown area on the interannual variability of the total output and the technical level, social and meteorological factors (especially meteorological factors) were analyzed respectively The Impact of Inter-annual Changes in Grain Yield. The results show that the main reason causing the fluctuation of grain output in Jiangsu Province is the meteorological conditions. On this basis, from the perspective of mitigating meteorological disasters, the grain production in Jiangsu Province is analyzed and corresponding measures are put forward.
