| 摘 要： | 以湛江特呈岛红树林区为考察对象,通过底泥TOC向上覆海水释放的模拟对比实验,研究了红树林区底泥中TOC的释放规律和泥水比、温度、pH值三个环境因子对TOC释放的影响,同时对静态和动态体系底泥TOC的释放进行了对比。结果表明,静态下,不同条件释放规律一致,上覆海水TOC的变化呈近似"W"的趋势;泥水比增大会使底泥向上覆海水的TOC释放量增加;温度对底泥TOC释放的影响较为复杂,上覆海水温度较高或较低都有利于底泥TOC的释放;碱性条件有利于沉积物中TOC的释放;海水的运动对沉积物TOC的释放有很好的促进作用。

| Abstract: | Contrastive simulation experiment was done to study the release of total organic carbon(TOC) from mangrove sediment at Techeng Island of Zhanjiang,Guangdong Province and influence factors including proportion of mud and water,temperature and pH.The release behaviors in static and dynamic state were also compared.Results showed that the release law was accordant in different conditions and the change of TOC value of overlying seawater was nearly in shape of W in static state.TOC release amount increased with... |
