Abstract

To enhance absorption of air pollution within city landscapes，resistance and absorption of 38 important landscaping plant species in Zhejiang Province were measured after subjection to gaseous hydrogen fluoride（HF） fumigation. A linear correlation analysis was conducted between resistance and absorption，and then these parameters were divided into 5 levels from strong （5） to weak （1） for a cluster analysis. Results showed plants with a range of resistances to F from the strongest with Ophiopogon japonicus，which resisted 9 h of fumigation to the weakest with Liquidambar formosana，which resisted only 2 h. For deciduous plants the weakest resistance levels （1 and 2） were found in 87.50% of the specimens，whereas evergreen plants were spread fairly evenly in levels 1 to 4. Absorption of plants ranged widely with the greatest in Zelkova serrata having 13.66 g·kg－1 HF；this was 116.65 times more than Pinus elliottii，which had the least absorption with 117.06 mg·kg－1 HF. For deciduous plants，37.5% of the specimens were found in absorption level 3 with decreasing amounts in the stronger and weaker levels；whereas with evergreen plants，the percentage of specimens continually decreased from the weakest to the strongest levels. Also，there was no significant linear correlation between resistance and absorption of plants.［Ch，2 fig. 5 tab. 13 ref.］
