摘要:以 2007 年长岛县海岛调查资料为基础,分析了长岛县海岛潮间带沉积物中重金属含量特征及其与有机质含量等之间的相关关
系,并对其潜在生态危害进行了评价。结果表明,所有海岛潮间带重金属元素含量均未超过环境背景值;不同海岛间潮间带沉积物中重金属
元素与有机质的关系略有差异;长岛县海岛潮间带重金属具有轻微生态危险,该海区可适当发展养殖业和旅游业。

Abstract:Based on the survey data of islands in Changdao County in 2007,characteristics,relations anic matter and
potential ecological risks of heavy metals in intertidal sediments of the island were analyzed. Results showed that the content of
heavy metals were lower than the background value in all islands. Relationships of heavy metal anic matter were various
between different islands. Heavy metals in intertidal sediments have slight ecological risk,which indicated that breed aquatics
and tourism could be developed in the area.
Key words:islands in Changdao County;intertidal zone;heavy metal;potential ecological risks
