摘要
利用凤阳县1949~1992年烤烟草产资料,划分出该县烤烟产量丰歉年景,运用谐波分析法分析了烤烟单产效收或严重欲收年景与气象灾害的关系及其随时间变化的规律,并尝试预测未来若干年内气象灾害年的分布。在上述分析的基础上,探讨了减轻气象灾害的相应对策。
Five categories of year's harvests, i. e. best, good. normal, poor and worst, were divided based on the yield data per unit area of flue-cured tobacco from 1951 to 1990. in Fengyang County, Anhui Province.Poor or worst year's harvests in relation to meteorological disasters, and laws of changes with years were analysed by adopting the harmonic method. An attempt to predict the distribution of meteorological disasters in future was made and corresponding measures were studied.
