根据国家环境保护局的资料,我国的酸雨日趋严重。四川、贵州、广西、广东、湖南、湖北、江西都有酸雨,其中尤以四川、贵州两省更为严重。近年来,酸雨出现频率在柳州、重庆近90%,南昌90%以上,贵阳70%以上,宜昌近70%。酸雨对农作物、森林等产生很大的危害。贵册酸雨受害地区森林材积损失率达15.4%,重庆为22.15%。重庆帝因酸雨而导致蔬菜减产24.4%,重庆市南岸、沙坪坝、江北、九龙坡等近郊及郊县水稻减产22.7%、玉米减产29.6%,小麦减产14.4%。四川峨嵋山森林成片枯萎,在相当大的程度上也同酸雨有关。现在,中国西南地区已经成为与欧洲波罗的海沿岸、北美五大潮沿岸并列的世界三大酸雨区之一。酸雨所造成的直接和间接经济损失,目前还没有较精确的估计。森林的破坏、农作物的减产、水产资源的受损失、建筑物的受
According to the information of the State Environmental Protection Administration, the acid rain in our country is worsening day by day. There are acid rain in Sichuan, Guizhou, Guangxi, Guangdong, Hunan, Hubei and Jiangxi, especially in Sichuan and Guizhou provinces. In recent years, the frequency of acid rain appears in Liuzhou, nearly 90% in Chongqing, more than 90% in Nanchang, more than 70% in Guiyang, and nearly 70% in Yichang. Acid rain on crops, forests, etc. have a great impact. In the area affected by acid rain, the volume loss of forest products is 15.4% and that of Chongqing is 22.15%. Due to the acid rain in Chongqing, vegetables were reduced by 24.4%. The output of paddy in suburbs and suburban counties such as Nanping, Shapingba, Jiangbei and Jiulongpo in Chongqing decreased by 22.7%, that of maize by 29.6% and that of wheat by 14.4%. Sichuan Emei Shan forest withered, to a considerable extent also with the acid rain. Now, southwestern China has become one of the world’s three major acid rain areas along the Baltic coast of Europe and the five major tide coasts of North America. There are no more accurate estimates of the direct and indirect economic losses caused by acid rain. Destruction of forests, crop production cuts, loss of aquatic resources, and building damage
