气象灾害对凤阳县烤烟质量的影响及防灾减灾对策

Effect of Meteorological Disasters on Quality of Flue-Cured Tobacco and Countermeasures

利用安徽省凤阳县1955～1996年烤烟上中等烟比重资料，划分出该县烤烟质量优劣年景．采用统计学方法研究烤烟质量与气象条件的关系，结果表明：旱涝灾害、成熟期高温热害和强烈日照是造成凤阳烤烟劣质的主要气象灾害．运用谐波分析法分析了烤烟劣质或严重劣质年景与气象灾害的关系及其随时间变化的规律，并尝试了预测未来若干年内气象灾害年的分布；探讨了防灾减灾对策．

Five categories of good-poor years,i.e.best,good,normal,poor and worst,were divided based n quality data of flue-cured tobacco in Fengyang County,Anhui Province,from 1957 to 1990.Statistical analysis revealed the average diurnal temperature and sunshine in mature period were the major meteorological factors influencing on tobacco quality.Poor or worst years in relation to meteorological disasters,and laws of change with years were analysed by adopting the harmonic method.The distribution of meteorological disasters in the future is predicted and the corresponding countermeasures is studied.
