| 摘 要： | 通过表层沉积物粒度测试、重金属测试及相关分析、大比例制图,对莱州浅滩及附近海域海底表层沉积物重金属含量分布与动力沉积环境关系进行了研究.结果表明,与区域动力沉积格局对应,浅滩及附近海域表层沉积物各元素含量呈现出中部低、两侧高的马鞍型分布格局,即动力较强的浅滩东北侧低于动力较弱的西南侧,而动力最强的浅滩顶部又低于浅滩东北侧.其中,受浅滩两侧两个潮余环流控制,浅滩两侧各重金属含量均呈现出中心高、周围低的向心状分布格局.但是,重金属含量分布并不完全对应于区域动力沉积格局,且不同元素间有显著差异.

| Abstract: | On the basis of high density sampling,granularity testing,heavy metal content testing and large-scale geochemistry map drawing of the surface sediments,we researched the content and distribution characteristics of heavy metals of surface sediment in the Laizhou shoal and its surrounding region.The results show that(1)controlled by the regional dynamic environment,the content of every heavy metal presents a notable saddle-shaped regional distribution pattern with a low content area with the strongest dynamic... |
