摘要:
1996-1997年度衡阳大气硫同位素监测结果是:大气降水δ(34S)均值为6.12‰,大气二氧化硫δ(34S)均值为-3.48‰,大气气溶胶δ(34S)均值为10.73‰.数值体系较好地符合硫同位素分馏规律,研究认为,该地大气环境受西南气流影响甚微,北方南下气流进一步推断为作用该地大气硫的主因;生物硫源对降水硫影响不容忽视;衡阳与珠江三角洲及粤北城市硫同位素监测结果均不支持降水硫同位素区域分异学说.

Abstract:
The monitoring result of atmospheric sulfur isotopic composition in Hengyang from 1996 to 1997 is as follows:atmospheric precipitation δ( 34S) average value is 612‰,atmospheric SO\-2 δ( 34S) average value is-3\^48‰,and atmospheric aerosol δ( 34S) average value is 10\^73‰.The numerical value is in accordance with the rule of fractionation of sulfur isotope.The research holds the viewpoints that southwest airstream exerts little influence on Hengyang’s atmospheric environment,and the southing airstream from the north is further inferred to be the main cause influencing local atmospheric sulfur.The influence of biogenic sulfur fountain on precipitation cannot be ignored.Sulfur isotopic monitoring results in Hengyang,Pearl River delta and cities in the north part of Guangdong do not hold out the theory of precipitation sulfur isotope area differentiation.
