未来气候变化时南京地区冬小麦气候生产潜力估算

近代有关于ＣＯ２甑上气候变化趋势以及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主其对小麦影响的基础上，综合评价了气候对小麦的影响，提出了ＣＯ２地南京地区小麦气候生产潜力的估计值。

Estmation of Production Potential of Wheat in Nanjing as Influenced by Future Climatic Changes

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.
