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.
