Temporal-Spatial Variation Characteristics of Acid Rain during 2007 to 2012 in Fujian Province

Abstract:

Based on the meteorological observation data of 4 acid rain monitoring stations (Shaowu Station, Fuzhou Station, Yong’an Station and Xiamen Station) during 2007 to 2012 in Fujian Province, the characteristics of the acid rain were analyzed. The results showed that acid rain pollution was common in Fujian Province while showing a reducing trend overall. The time from 2007 to 2010 was acid rain pollution period of large precipitation acidity and high strong acid rain frequency. And the time from 2011 to 2012 was acid rain improving period with precipitation acidity weakening and strong acid rain frequency declining. It showed an obviously seasonal feature for acid rain. Acid rain pollution was relatively heavy in winter while light in summer in Fuzhou, Shaowu and Xiamen. But the seasonal distribution in Yong’an was just the opposite. There were large differences in the degree of acid rain pollution in different regions. The acid rain pollution in Shaowu was heaviest belonging to the strong acid rain area. And the second was Fuzhou belonging to the moderate acid rain area. Xiamen and Yong’an belonged to the light acid rain area with lighter pollution. The acid rain pollution showed various degrees of improvements in Shaowu, Fuzhou and Xiamen. Especially in Fuzhou the improvement was particularly evident as the best condition in recent years. While in Yong’an the acid rain pollution had aggravated somewhat in recent years with the acid rain frequency increasing and the precipitation acidity enhancing.
