摘要
近代科学家关于ＣＯ２倍增情况下气候变化趋势以及对小麦影响的研究均忽略了太阳紫外辐射变化及其对小麦的影响。试验结果表明，未来太阳紫外辐射增加对小麦产生很大影响，导致小麦植株变矮、长势变差、生理活动受阻、产量下降。在考虑了太阳紫外辐射变化及其对小麦影响的基础上，综合评价了气候变化对小麦的影响，得出了ＣＯ２倍增时南京地区冬小麦气候生产潜力的估计值。
Change in sloar UV radiation and its effect on wheat growth have not received adequate attention in studies investigating the changing trend of climate resulting from CO 2 doubling and its influence on wheat. Our experiments showed that enhanced solar UV radiation could produce negative effects on wheat, leading to shortened plants, poor growth, inhibition of normal physiological activites and decrease in yield. Based on the overall evaluation of climatic changes, including solar UV radiation, on wheat production, estimates of climatic production potential were obtained for winter wheat grown in Nanjing under doubling CO 2 concentration.
