摘要
滨海湿地作为海陆物质交换的敏感区,其中硫等生源要素的迁移转化过程对于湿地物质循环等具有重要的环境意义。基于此,本文选择典型滨海高硫湿地北大港湿地作为研究对象,探讨了北大港湿地沉积物土样的理化性质和无机硫形态垂直变化规律。结果发现垂向剖面上水溶性硫和吸附性硫具有显著的空间变化特征,并且硫含量高的表底层沉积物分别受不同硫来源和硫转化过程的影响。研究结果对滨海湿地硫酸盐转化提供数据支持和理论依据。
Coastal wetland is a sensitive area for land and sea material exchange, and the migration and transformation process of biogenic elements such as sulfur has important environmental significance for wetland material circulation. Based on this, this paper selects the typical coastal high-sulfur wetland Beidagang Wetland as the research object, and discusses the physical and chemical properties and the vertical change of inorganic sulfur forms of the sediment soil samples in Beidagang Wetland. The results show that water soluble sulfur and adsorbed sulfur have significant spatial variation characteristics in the vertical profile, and the surface and bottom sediments with high sulfur content are affected by different sulfur sources and sulfur conversion processes respectively. The research results provide data support and theoretical basis for sulfate transformation in coastal wetlands.
