摘　　要：通过对既是典型的酸沉降污染区又是典型石灰岩地区的柳州进行的２次野外植物伤害考察发现，在被调查的４３６种植物中，８４种受到酸沉降污染轻度伤害，３０种受到重度伤害。经分析表明，石灰岩植物比非石灰岩植物对酸沉降敏感；落叶植物比常绿植物对酸沉降敏感。市区内濣地大气中ＳＯ２含量高于远郊区是市区内行道树严重受害的主要原因之一。Field investigations on plants damaged by acid deposition were carried out for 2 times in Liuzhou,both a typical acid deposition area and a typical limestone area. The results of investigation are as follows, among the 436 species of plants investigated, 84 species are damaged triflingly and 30 species are damaged seriously by acid deposition. The limestone plants are more sensitive than nonlimestone plants,and the deciduous plants are more sensitive than the evergreen plants.One of the main reasons cause the road tree damaged is that the SO2 concentration at down town is higher than it at suburb.
