摘要
在分析测试几种植物叶片含硫量基础上,通过与大气SO_2浓度相关性分析,得到几种植物吸收SO_2量与大气SO_2浓度呈相关关系的事实。进而从植物对净化的吸附、积累等基本过程,并结合绿地调查,对大连市区绿地净化空气,保护环境的作用作以探讨。
Besed on the measurement ot leaves sulfur content of several plants inDalian City,some correlations between SO_2 absorbed by plant and SO_2 inatmosphere is set up.According to these basic courses:SO_2 absorption andaccumulation by leaves,and the investigation of vegetation area in the city,anassessment of the total SO_2 purification amount,about 1,137 tons over the areaper year,is suggested.
