摘要: 本文对厦门市5个样点、6种常见绿化树种及盆栽植物蕹菜的叶绿素含量、叶片含硫量及大气中SO2浓度分析测定,得出了6种植物叶绿素a、b变化趋势是:鼓浪屿、厦门大学>火车站、后江埭>电化厂;叶片含硫量的变化趋势与叶绿素a、b含量变化相反。表明植物叶片叶绿素含量与大气中SO2浓度和叶片含硫量呈负相关,并计算蕹菜叶绿素含量与大气SO2浓度相关模式(y=-0.0138x+0.1958),为大气环境评价提供生物学依据。

Abstract: Contents of chlotophyil and Sin leaves of six afforested trees and sand culture plant (Ipomoea aquatica) and concentration of SO2 in air were determined at five sites of Xiamen City. Chlorophyll a and b showed a decrease in the order of Gulangyu,Xiamen University>Train Station>Houjiandi Industry District>Electrical Chemical Factory,but Chl. a/b and Scontent in leaves showed a reversed tendency. These indicated that content of chlorophyll in leaves was negatively correlated with eoneentraion of SO2 in air and Sin leaves. The correlation equation was calculated(Y=-0.0138x+0.1958)to monitor concentration of SO2 in air by content of chlorophyll in plant leaves,which shows a biological evidence in evaluating air quality.

Key words: Chlorophyll, SO2, Ait pollution, Plant monitoring
