| 摘 要： | 在广西龙门岛潮间带取得了长度为97 cm的LM01柱,在210Pb定年的基础上对沉积物的粒度、生源要素(TOC、TN、TP)、油类以及重金属(Hg、Cu、Pb、Zn、Cd、Cr和As)等指标进行了综合分析.研究发现.潮间带沉积物的粒度在近60年来有明显的"细化"趋势;各种污染要素的含量在近30年来也急剧增加,但仅Cu和...

| Abstract: | A sediment Core LM01 was collected in May,2007 from the intertidal zone of the Longmen Island,Guangxi province.Grain size,biogenic elements(TOC,TN and TP)and heavy metals(Hg,Cu,Pb,Zn,Cd,Cr,As)were analyzed for the core sediment in order to study the environmental evolution in the recent 150 years.Vertical grain size distribution shows a finer trend upwards from 40 cm in depth,indicating the decrease in sedimentary dynamics in the recent 60 years.Enrichment factors indicated that natural inputs prevailed up ... |
