摘要: In this study, the functional group concept was first applied to evaluate ecosystem health of Bohai Bay. Macrobenthos groups were defined according feeding types and divided into five groups: a carnivorous (CA), omnivorous (OM), planktivorous (PL), herbivorous (HE), detritivorous (DE). Groups CA, DE, OM, PL identified, but HE absent from Group DE dominant during study periods. The assessed using evenness index. values most sampling stations less than 0.40, indicating that deteriorated in Such deterioration could be attributed land reclamation, industrial sewage effluents, oil pollution, hypersaline water discharge. This demonstrates can assessment semi-enclosed bay.
