Based on the data obtained from four cruise investigations during 2016-2017, the secondary production and the P/B ratio of the macrobenthos in Jiaozhou Bay were analyzed using Brey's empirical formula (first devised by Brey in 1990), and the relationship between environmental factors and secondary productivity was analyzed with Pearson's correlation. The results showed that the annual mean abundance was 19.17 ind/m², mean biomass in ash-free dry weight (AFDW) was 20.57 g/m², mean secondary productivity in AFDW was 9.64 g/(m²·a), and the mean ratio was 0.47/a. In terms of spatial distribution, sampling stations with high secondary productivity were mainly located in areas near aquaculture systems and coastal sea areas, highlighting these as high productivity centers. For seasonal distribution, the seasonal variation of secondary productivity was spring > winter > summer > autumn. The correlation analysis indicated that the relationship between environmental factors and secondary productivity was not significant (>0.05). The secondary productivity near the aquaculture area in the bay was closely correlated with sediment type, while being greatly correlated with dissolved oxygen outside the bay. Comparing the results of the present study with other similar studies, secondary productivity in Jiaozhou Bay was higher than that of most sea areas of North China, but the ratio was lower. The results showed that species with small body size, short life and quick metabolism were accounted for less in the community composition of Jiaozhou Bay.
