广州城市建成区绿地对大气二氧化硫的净化作用

The Role of Guangzhou Urban Vegetation in Removing Atmospheric Sulfur

研究广州城市建成区绿地植物的硫贮量和净生产量中的硫量，从而讨论城市绿地植物对大气中硫的净化作用．结果表明：建成区绿地植物的净生产量为６４９４８ｔ／ａ，净生产量中的硫量为４０９５６ｋｇ／ａ；净生产量中的硫量接近城市上空的平均硫贮量（４２６９０ｋｇ）．

The paper deals with the roles of urban vegetation in removing atmospheric sulfur by studying its sulfur storage and sulfur mass in net primary production (NPP) in Guangzhou. The results show that the sulfur in atmosphere is renewed once a year by the vegetation if the sulfur mass in NPP is mainly from atmosphere.
