摘　　要：通过对河南省气象台站观测的酸雨资料进行分析研究,揭示了河南省酸雨时空分布规律,即河南省酸雨出现频率西部大于东部,南部大于北部,秋、冬两季出现频率相当,春、夏两季相当,并且秋、冬季明显要高于春、夏季。在此基础上,分析了酸雨对各个生育时期的小麦和玉米的影响,以及酸雨通过对土壤的影响进而对农作物产生的危害。Based on the acid rain data coming from Henan provincial meteorological observatory, the paper showed the regulation of temporal and spatial distribution of acid rain in Henan. The frequency that acid rain appeared in western region is higher than in eastern region, and in southern region is higher than in northern region. The frequency in autumn is equivalent to that in winter, and the frequency in spring is equivalent to that in summer, and in autumn and winter is higher than in spring and summer. The influence of acid rain on different developmental phase of wheat and corn was analyzed. Also the influence of acid rain on soil is the bane of the farm crop.
