2、度指数分析潮间带大型底栖动物物种多样性和群落种类组成,并对大型底栖动物的群落结构进行了初步研究。调查获得嵊泗海岛的不同底质潮间带大型底栖动物130种,其中多毛类31种,软体动物57种,节肢动物32种,棘皮动物4种,其它类6种。春、秋季嵊泗潮间带大型底栖动物多样性指数(日’)(F。,=0.10,P=0.75)、物种丰富度(D)(F。,=0.66,P=0.43)和均匀度指数(,)(F¨,=0.33,P=0.58)均无显著差异;不同底质嵊泗潮问带大型底栖动物多样性指数(H’)(F。。=14.28,P3、而均匀度指数(-,)(F。,=1.62,P=0.23)无显著差异。群落结构聚类分析和MDS标序表明,8个取样站的群落可分为3组(工、Ⅱ和Ⅲ组)。根据所调查嵊泗海岛潮间带的丰度和生物量资料做的ABC曲线分析表明,底栖动物群落受到了中等程度的污染或者扰动[动物学报53(6):1000—1010,2007]。关键词潮间带一大型底栖动物多样性嵊泗群落生态MacrobenthoscommunitypatternsintheintertidalzoneoftheShengsiarchipelagoinspringandautumn“LIAOYi.Bo,ZENGJiang.Ning,C4、HENQuan—Zhen+。,GAOAi—Gen,SHOULu,XUXiao—QunKeyLaboratoryofMarineEcosystemandBiogeoehemistryofSOA,SecondInstituteofOceanographySOA,Hangzhou310012,Zhejiang,ChinaAbstractBasedonmacrobenthicsamplescollectedfrom8intertidalstationsintheShengsiarchipelago(Sijiaoshan,Gouqidao,HuaniaoshanandDayangs5、han)duringSept.2006andApr.2007,themacrohenthiccommunitywasanalysizedusingPRIMER5.0,ofwhichCLUSTER,MDS,DIVERSEandABCfunctionswereadopted.130specieswerefoundinthefourlocations,including3lspeciesofpolychaeta,57speciesofmollusc,32speciesofcrustaceanand6speciesofechinoderm.Thediversityindexwas6、notsignificantlydifferentinspringversusautumn.butitdifferedbetweensubstrates.%eresultsofCLUSTERandMDSanalysisshowedthatthemacrobenthiccommunityofintertidalzoneoftheShengsiArchipelagoconstitutesthFeegroups,namely,Igroup,includingstationsGS,SSandHS;Ⅱgroup,includingstationsDS;mgroup,includin7、gstationsDR,GR,HRandSR,Z西eresultsoftheABCanalysisindicatethatthemacrobenthiccommunityhasbeenaffectedbypollutionandotherhumanactivitiesActaZoologicaSinica53(6):1000—1010,2007I.KeywordsIntertidalzone,Macrobenthicfauna,Diversity,ShengsiArchipelago,Communityecology潮间带是受
