摘　　要：根据2011年6月和9月2个航次在东营市河口区潮间带开展的大型底栖动物调查,对春、秋季节不同断面的大型底栖动物的种类组成、群落结构作了分析。结果表明河口区潮间带大型底栖动物共有29种,包括软体类13种,甲壳类11种,多毛类3种,鱼类2种。春季调查中优势种是泥螺Bullacta exarata、文蛤Meretrix meretrix、彩虹明樱蛤Moerella iridescens、日本镜蛤Dosinorbis japonica、托氏琩螺Trochus vesriarium、焦河蓝蛤Potamocorbula ustulata和豆形拳蟹Philyra pisum,秋季仅有四角蛤蜊Mactra veneriformis一个优势种。Based on the data collected from the 9 sampling stations in spring to autumn 2011.29 species were found and analyzed into 4 classes,including 13 species of Molluse,ll of Crustacea,3 of Polychaeta,2 of fish. The dominant species in spring are Bullacta exarata ,Meretrix meretrix, MoereUa iridescens, Dosinorbis japonica, Trochus vesriarium, Potamocorbula ustulata and Philyra pisum. The dominant specie in autumn is Mactra veneriformis. The results of CLUSTER analysis show that the structure of the macrobenthic communities in the 9 stations between the two seasons is not very unified.
