| 摘 要： | 利用我国历年烤烟单产资料 ,划分我国烤烟单产气候性增减及丰歉年景。对减产年景因不利的气象条件所造成的烤烟减产量及其中歉收年景因气象灾害所造成的烤烟损失量进行了估计 ,结果表明 :在 1 95 1～ 1 993年共 43年中 ,我国烤烟减产年景的气候减产量共计 99.32万吨 ,价值 1 4 .70亿元 ,平均减产 4.97万吨 ,价值 0 .74亿元 ,减产率平均 9.78% ;其中歉收年景的气象灾害损失量共计 5 8.2 4万吨 ,价值 7.97亿元 ,灾损量平均 9.71万吨 ,价值 1 .33亿元 ,灾损率平均 2 4.38%

| Abstract: | Flue-cured tobacco yield loss in low yield years due to unfavorable climate conditions ofr in poor harvest years due to meteorological disasters werw assessde.Five categories of harvest years were classified using actual yield data from 1951 to 1993 in China,i,e,very good,good,normal,poor and bad.Results show that annual yield loss in low yield years due to unfavorable climate conditions account for about 9.78% annually,which is 49700 tons on average and 7351400 Chinese yuan yn value.The annual yield loss in poor and bad years due to meteorological disasters account for about 24.38%annually,which is 97100 tons on average and 132868000 Chinese yuan in value. |
