| 摘 要： | 全球和区域大气环境研究的重要任务之一是查明各种气态物质自然源释放通量,含硫化合物是其中的一种,它在阐明生物圈硫循环和环境酸化中起重要作用.迄今为止,我国尚无有关研究报道.本文参考文献资料和实测数据用类比法进行了我国两广地区自然源硫化物释放量的计算.结果表明,天然源硫化物中主要是来自树木和土壤,释放的硫化物为COS(49％),DMS(32％)和H_2S(14％).两广地区全年自然源硫释放量3325吨(以硫计).

| Abstract: | Ascertaining the natural emissions of various gases is one of the important missions of the global and regional atmospheric environmental research. Sulphureous compounds of natural sources play an important role in sulphur cycle and environmental acidification. So far, papers concerning this area have been rare in China. In this paper, natural sulphur emission inventory has been developed using an analogism with references and field measured data. Results show that COS (46%), DMS(35%) and H2S (14%) are major sulphureous components of natural sources. Trees and soils are estimated to be the major natural sources. The natural sources annually contribute 3325 metric tons of sulfur in Guangdong and Guangxi. |
