在小麦生长发育的数值模拟研究的基础上，将小麦生育期划分为4个阶段，分别制定了数学模型和子程序，确定模型的参数，模拟出每一阶段的生育期天数，并且就每一阶段的温光条件对生育期各阶段的影响给出了分析与决策。该系统对了解小麦生长发育与气象条件的定量关系，对不同发育期小麦采取有效的措施具有参考意义，也是计算机应用于小麦生产的一种尝试。系统采用中文菜单操作，界面友好，可人机交互。结构化、模块化技术使系统具有易于修改、扩充的特点。

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.

地表紫外辐射强度计算的准确与否，直接关系到紫外辐射指数（UVI）预报的准确性，其计算方法受到气象部门的特别重视。采用简化大气辐射计算模式、离散坐标（DISORT，discrete-coordinate-method）辐射传输算法、气候学经验模式及观测的方法研究了南京地区紫外辐射量的变化。计算与观测的比较显示，简化模式、DISORT 及气候学方法的计算值与观测结果具有较好的一致性。表明三种模型都具有一定的可靠性。

Studies on the effects of enhanced solar UV radiation on the growth and physiology of soybean and wheat show that under natural conditions, the increase of UV radiation can inhibit the net photosyntetic rate and the growth of leaves, stems and roots of both tested crops. The decrease of biomass and yield is caused by the decline of transpiration and stomatal conductance of leaves. Estination of the crop response on the enhanced UV radiation shows that the mean error between fitting value and observed one is 0.30～8.56%.
