2000～2002年惠安县降雨酸度报告及成因分析

2000-2002 year Huian county's rainfall acidity makes known and analysesthe contributing factor

目的:了解2000～2002年惠安县降雨酸度值。方法:连续三年采集183份降雨水样进行pH值测定。结果:pH≤5.6占57份,酸雨频率31.1%.春季酸雨占全年酸雨的82.5%。结论:酸雨与大气局部污染有关,大气环流对大气污染的中长远距离造成区域的背景酸度值值得探讨。

Objective: Comprehend 2000-2002 year Huian county's rainfall acidity. Methods; Was collected 183 rainfall water shapes in successive 3 years and is carried on PH's value measurement. Results: pH≤5. 6 seize 57, acid rain frequency 31. 1% springtime the acid rain seizies 82. 5% If yearly acid rain. Conclusion: Acid rain against the air partly contaminates having something to do with.and that air circulation adjust the backdrop acidity that the long-term distance areated the area in the atmospheric pollution merit the inquirement.
