摘要
对江苏省南京地区春大豆的生产潜力进行估算，并分析了未来气候条件下，大豆生产潜力的变化情况。除了考虑温度、降水、ＣＯ２等影响因子之外，还考虑了未来地表紫外线（Ｕｌｔｒａｖｉｏｌｅｔ简称ＵＶ）辐射增加对大豆的影响。研究结果表明：在未来气候条件下，江苏省南京地区春大豆的气候生产潜力呈下降趋势。
The potential productivity of spring soybean in Nanjing is calculated and the changes of soybean potential productivity under the climatic conditions in the future is analyzed. In addition to temperature, precipitation, and CO 2 concentration, the effect of enhanced ultraviolet reached on earth’s surface in the future on the growth and yield of soybean is stressed here. The results revealed that under the climatic conditions in the future, the potential productivity of spring soybean in Nanjing aera of Jiangsu Province will present decreasing trend.
