摘    要:为了解黄河入海口潮间带大型底栖生物现状,于2008年和2009年黄河枯水期的5月和丰水期的8月分别对黄河入海口5条潮间带断面大型底栖动物进行了采样调查。结果表明,采集到大型底栖动物65种,其中软体动物26种、甲壳动物22种、多毛类12种、腔肠动物2种、腕足动物、棘皮动物和鱼类各1种。软体动物和甲壳动物是构成潮间带底栖动物的主要类群。黄河入海口潮间带大型底栖动物平均栖息密度为(929.60±356.53)/m2,平均生物量(湿重)为(169.92±7.31)g/m2。在栖息密度组成中,软体动物占绝对优势,其次甲壳动物和多毛类,其他类群较低。Shannon-Weiner多样性指数为1.44±0.44,Margalef物种丰富度指数1.57±0.15,Pielou均匀度指数0.42±0.11。年平均去灰干重(13.96±0.61)g(AFDW)/m2,年次级生产力(11.26±0.62)g(AFDW)/(m2.a),P/B值平均(0.89±0.11)/a,表明黄河入海口潮间带个体较大、生活史较长的大型底栖动物种类所占比例较高。

关 键 词:大型底栖动物  群落组成  次级生产力  潮间带  黄河入海口

Abstract:In order to understand the present status of macrozoobenthic fauna in the intertidal zone of Yellow River Estuary,four surveys were made at 5 sections of the zone in May and Aug.of 2008 and 2009.A total of 65 macrozoobenthos species were recorded,including 26 species Mollusc,22 species Crustacea,12 species annelid polychaete,2 species Coelenterate,1 species Brachiopoda,1 species Echinoderm and 1 species fish.The dominant species were Mollusc and Crustacea.The inhabit density and biomass(fresh weight) of macrozoobenthos were(929.60±356.53)/m2 and(169.92±7.31)g/m2 respectively.The dominant inhabit density species were as follows: Mollusc > Crustacea and annelid polychaete > the other kinds.The mean Shannon-Weiner index was 1.44±0.44 when the mean Margalef species richness index and the mean Pielou evenness index were 1.57±0.15 and 0.42±0.11 respectively.The mean ash free dry mass per year was(13.96±0.61)g(AFDW)/m2 with the secondary production and the mean P/B value being(11.26±0.62)g(AFDW)/(m2·a) and(0.89±0.11)/a respectively,which showed that the dominant species of macrozoobenthos in the intertidal zone of Yellow River Estuary was the big ones with a longer life cycle.
Keywords:macrozoobenthos  community structure  secondary production  intertidal zone  the Yellow River Estuary
