| 摘要: |
| 以中国红树林主要分布地区——海南、广东、广西、福建的13个红树林区为研究对象,对沉积物中硫的分布特征及相关影响因素进行了分析。中国红树林地区沉积物中硫含量为0.009%~0.809%,平均含量为0.214%,远高于非红树林生长地区沉积物中硫的平均含量。海南、广东、广西、福建四省区红树林沉积物中硫的平均含量分别为：0.34%、0.19%、0.20%、0.18%。13个地区含硫量高低顺序为：三亚、东寨港、云霄、钦州、俄湾、姚家屿、高桥、山口、大冠沙、北仑河口、福田、洛阳桥、浮宫。各个不同红树林地区沉积物中的硫含量差异显著。硫含量与有机质含量、盐度显著正相关,与pH值显著负相关。土壤粒度组成以及铁含量对土壤中全硫含量有一定的影响。

| Abstract: |
| Thirteen important mangrove areas including Hainan, Guangdong, Guangxi, Fujian were studied, and distribution and influential factors of sulfur were discussed. Total Sulfur (TS) content ranged 0.009%~0.809%, with an average value of 0.214%, which was much higher than that in the sediments without mangrove. The TS concentrations in Hainan, Guangdong, Guangxi and Fujian were: 0.34%, 0.19%, 0.20% and 0.18% respectively. The order of TS concentration in sediments of these mangrove wetlands decreased:Saiao>Qinzhou>Ewan>Yaojiayu>Gaoqiao>Shankou>Daguansha>Beilunhekou>Futian>Luoyangqiao>Fugong. Organic matter and salinity correlated significantly with the TS concentration in sediments; pH correlated negatively with the TS concentration. Size fraction and iron content also influenced TS concentration in sediments.
