摘　　要：根据2011-2013年每年8月昌黎生态监控区大型底栖动物监测数据,以Simpson优势度为指标分析了研究区大型底栖动物的物种组成及群落结构年际变化。运用物种多样性指数(H')、均匀度指数(J)、丰富度指数(dMa)深入探究了监控区底栖动物的多样性变化趋势。研究结果显示:1)多毛类、甲壳类、软体类动物是该海域大型底栖动物的主要类群;2)2011-08监控区平均密度为43个/m2,平均生物量为3.14g/m2;2012-08监控区平均密度为41个/m2,平均生物量为3.21g/m2;2013-08监控区平均密度为28.74个/m2,平均生物量为7.72g/m2;3)2013年监控区19个站位多样性指标均值远高于前两年;4)2011-08监控区第一优势种为绒毛细足蟹其Y值为0.029 4;2012-08监控区第一优势种为裸盲蟹其Y值为0.007 3;2013-08监控区第一优势种为长吻沙蚕其Y值为0.007 0。According to the data of Cangli ecological monitoring area collected in every August from year 2011 to 2013,this article analyzed the annual variation of macrozoobenthos species composition and community structure by using Simpson dominance index （Y） as an indicator,and discussed the variation trend of macrozoobenthos by using Shannon-Wieners index（H＇）、Peilou＇s evenness index（J） and Margalef＇s richness index（dMa）.Results showed that：1）Aglaophamus dibranchis,Amaeana occidentalis and Nephtys polybranchia were the dominant species in this area; 2）The average density of macrozoobenthos in this area was 43 ind/m^2 and average biomass is 3.14 g/m^2 in August,2011;they were 41 ind/m^2 and 3.21 g/m^2 in August,2012;and 28.74 ind/m^2 and 7.72 gm^2 in August,2013,respectively;3）The mean value of the diversity index in August,2013 was much higher than those in two other years;4）The dominant species in August,2011 was Raphidopus ciliatus with a Simpson dominance index （Y） of 0.029 4; It was Typhlocarcinus villosus with a Y value of 0.007 3 in August,2012 and Glycera chirori with a Y value of 0.007 0 in August,2013.
