摘要
在介绍硫的生物地球化学循环的基础上，概述了几种挥发性有机硫气体ＤＭＳ，ＣＯＳ，ＭＳＨ，ＣＳ２和ＤＭＤＳ从各种自然源（主要是生物源）释放的情况，着重阐述了陆地生态系统中各种生物硫源的释放情况，列举了测定这些释放的硫通量的方法，并且对有机硫气体的大气行为及环境影响也作了论述。
The biogeochemistry cycle of sulfur was introduced,emission situation of several volatilesulfur gasesDMS,COS,MSH,CS,and DMDS from some natural sources (espeeially biologi-cal source)are summarized.Then,the emission situation of varioaus biological sources in ter-ristrial ecosystem was focused,the measurement methods of these sulfur emission fluxeswere enumerated ,and the atmospheric behavior and envirbnmental influecce of volatile sulfurgases were discussed.
