摘要
本研究通过模拟试验和现场调查,确立两广地区主要农作物对酸性降水、SO_2单一污染,酸性降水与SO_2复合污染的产量反应生态基准值。根据酸性降水年均pH和SO_2年日均浓度等值线,农作物的空间分布,采用市场价格法,估算了酸雨引起两广地区农作物经济损失值。
The evaluation criteria of the yield losses of crops under SO2 and acid ram seperatly as well as combination of SO2 and acid rain had been established. The area of the yield losses covered by SO2 and acid rain was estimated according to the annual average pH of acid rain and the annual daily average concentration of SO2, The economic losses of crops caused by acid precipitation in Guangdong province and Guangxi Autinomous were estimated.
