观测分析了大田条件下UV-B 辐射增强对麦田中麦蚜的影响，结果表明UV-B 辐射增强，蚜虫发生总量、小麦植株发生的百分率显著降低，蚜虫在穗部和植株上部叶片的发生概率下降，但蚜虫在叶片背光面发生数量增多，小麦植株的虫害发生概率降低。

地表紫外辐射指数预报是国内专业气象台的主要业务之一，从建立地表紫外辐射预测和对策系统的必要性出发，阐述了该系统建立的原理、系统的结构和功能等。

在降低目前南京地区近地面紫外UV-B辐射强度15.3%的条件下，采用室外盆栽试验方法，研究了小麦的生长及产量的变化。试验结果表明，降低目前近地面紫外UV-B辐射强度，小麦的株高、叶面积、叶绿素含量、生物产量及经济产量均显著增加，而叶片类黄酮含量显著下降。 结果还表明，在小麦不同生育期降低目前近地面紫外UV-B辐射强度，小麦的产量增加幅度也有显著差异，表现为拔节—齐穗期>齐穗—成熟期>苗期。说明目前南京地区近地面紫外UV-B辐射强度对小麦生长及产量已构成一定程度的影响，且小麦拔节—孕穗期是对UV-B辐射的敏感时期。

The stratospheric ozone depletion and enhanced solar ultraviolet-B (UV-B) irradiance may have adverse impacts on the productivity of agricultural crops. The effect of UV-B enhancements on agricultural crops includes reduction in yield, alteration in species competition, decrease in photosynthetic activity, susceptibility to disease, and changes in structure and pigmentation. Many studies have examined the influence of supplemental UV-B irradiance on different crops, but the effect of UV-B irradiance on cotton (Gossypium hirsutum L.) crops has received little attention. Cotton is one of the most versatile of all the crops. It is a major fiber crop of the world and a major source of trade and economy in many countries. In this study, we provide quantitative examination of the effects of elevated UV-B irradiance on cotton plant (Sukang 103). The tested cotton crop was grown under natural and four regimes of supplemental UV-B irradiance in the field. With UV-B irradiance increased 9.5% throughout the growing season, the negative impacts on cotton growth included reductions in height of 14%, in leaf area of 29%, and in total biomass of 34%. Fiber quality was reduced and economic yield dropped 72%; an economic coefficient was reduced 58%. A brief discussion is included on how the impacts on cotton contrast with impacts that have been observed in other studies on other plants, including trees.

利用小麦灌浆期作物群体小气候观测资料分析研究了过量紫外线照射后农作物群体小气候（总辐射、紫外辐射、温度等）的时空分布特征，发现紫外辐射（UV-B）增强使小麦群体中下部的总辐射高于对照区（CK），不同处理组下部的总辐射日振幅不同：CK（无UV-B区）>T1（UV-B增强3.8%）>T2（UV-B 增强11.4%；小麦群体的紫外辐射强度在各个层次上均大于对照区；小麦群体的中下部温度明显高于对照区的温度，中上部反之，CK处理气温梯度远大于T2处理气温梯度。
