【摘要】 通过时１９８０－１９９０年期间一系列观测及统计资料进行综合分析后指出：８０年代我国云南的气候变化是以变暧和变干为主要特征；粮食产量与旱涝有很好的对应关系。有关研究结果还表明，在云南１２种农作物中，特别是大豆的产量，与大气臭氧变化及抵达地面的太阳生物有效紫外线（ＵＶ－Ｂ，２８０－３２０ｕｍ）辐照量之间有较为明显的相关。更多还原

【Abstract】 ased on the analysis of observational and statistical data series of 1980s, thecharacteristics of the ozone layer variation and climate evolution in Yunnan Provincehave been studied in the paper. The results show that in 1980s the climate in Yunnanhas become warmer and drier which has made a notable impact on grain production,kalso indicates that there is a certain relationship between the flooding /drought damageand the agricultural production. Especially , the soybeen production has an obviouscorrelation with the total ozone amount and the solar UV-B(280-32um)irradiance.更多还原
