摘要： 为了解威海近海人工鱼礁区的沉积环境质量，对该海域表层沉积物中的沉积要素的含量进行了分析，并对其进行污染评价。根据2011年11月，2012年4月、6月、8月、11月和2013年6月、8月共7个航次沉积环境要素调查资料，分析了威海近海人工鱼礁区表层沉积物中总氮、总磷、有机碳和硫化物含量的分布特征，并采用单因子污染指数法和内梅罗污染指数法对沉积物质量进行了评价。结果表明：研究海域表层沉积物中总氮、总磷、有机碳和硫化物的含量均较低，且有机碳和硫化物的含量均符合GB 18668—2002《海洋沉积物质量》中的第一类标准，并呈现出明显的月际变化。单因子污染指数分析表明硫化物和有机碳未对研究海域沉积物产生污染。内梅罗污染指数分析海域沉积物质量的结果表明，研究海域沉积物质量等级为Ⅰ级，且鱼礁区和对照区表层沉积物质量无显著差别。

Abstract: This study aimed to analyze the contents of sedimental elements in the surface sediments of Weihai offshore artificial reef areas and evaluate the pollution of sediments, thus to provide reference for understanding the quality of sedimentary environment in Weihai offshore area. Based on the investigation of the surface sediments in November of 2011, April, June, August and November of 2012, June and August of 2013, the distribution characteristics of total nitrogen, total phosphorus, sulfide and organic carbon were analyzed. The surface sediments quality was comprehensively analyzed using single factor pollution index and Nemerow pollution index. The results revealed that the contents of the total nitrogen, total phosphorus, sulfide and organic carbon were in accordance with the first class standard of the National Standard of Marine Sediment Quality (GB 18668—2002) and had an obviously monthly variation. The analysis of single factor pollution index indicated that the study area was not polluted by sulfide and organic carbon. The analysis of Nemerow pollution index showed that sediment quality in the study area was in accordance with the first class standard, and there was no obvious difference in sediment quality between artificial reef areas and the control areas.
