酸沉降对柳州主要乔灌木影响的研究

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.
