Long-term Effects of Penglai 19-3 Oil Spill Event on the Macrobenthic Community Structure in Bohai Sea
摘要
Abstract
[Objective]In order to understand the long term impact of Penglai 19-3 oil spill e-vent on benthic ecosystem since 2011,this research was arranged to study the present quality of benthic ecosystem in Bohai Sea.[Methods]The macrobenthic community was quantitative-ly researched based on data carried out at 32 sampling stations from August to September in 2014,Bohai Sea.[Results]191 macrobenthic species in total were obtained in 32 sites in Bohai Sea,most of the them belong to Polychaeta(83),Crustacea(40),Mollusca(42),and Echino-dermata (1 5 ). The dominanted species is molluscanMusculus senhousei (Benson,1842),as a disturbance tolerant species which could affect the stability of macrofauna community.The total mean abundance is 676.88 ind/m2 ,varies from 15 ind/m2 to 11 555 ind/m2,which is lower than the value of surveys result before the oil spill happened.The total mean biomass of this area reached 30.77 g/m2 ,varies from 0.09 g/m2 to 141.55 g/m2 ,which is higher than the previ-ous level before the oil spill happened.The main contributor of biomass value is from echino-dermata,while mollusca contributes the most to abundance value.Comparing to previous studys,the trend of macrobenthic miniaturization in body size seems to slow down.The mean value of Shannon-Wiener diversity index,richness index and evenness index was 3.11±1.20, 2.89±1.40 and 0.82±0.22,respectively.Abundance Biomass Curves indicated that the macrofauna communities in the research region had been in moderate disturbance.[Conclu-sion]It showed that macrofauna communities in oil spill areas had recovered to different de-gree in the past three year of oil spill events.关键词
