摘要
通过对植物叶片含硫量分析 ,对平顶山市绿化植物净化大气的效应进行了研究 .结果表明 ,平顶山绿化植物对大气SO2 的吸收总量为 16 4 .2 6 3t·a-1,其中叶片吸收 12 3.198t·a-1;枝干吸收 4 1.0 6 5t·a-1,乔木吸硫量占植物吸硫量总量的5 9.1% ,灌木占 4 0 .9% ,说明对大气SO2
Based on sulphur contents analysis in leaves,the depurative effect of plants on air pollution in Pingdingshan city were studied. The results showed that: currently the green plants can purify 164.263 t·a -1 of SO 2 in Pingdingshan city, among them leaves contribute 123.198 t·a -1 ,branch and trunk 41.065 t·a -1 . The depurative amount of SO 2 by trees and shrub takes up 59.1% and 40.9% of the total depunatire ancount respectively , it is obvious that trees are the main contributors to the purification of SO 2 in air.
