2、物門5種,占總物種數(shù)的26.32%。紅旗泡水庫的底棲動物優(yōu)勢種為截口土蝸G6ntruncatula及斯蒂齒斑搖蚊Stic—tochironomussticticus,而紅旗泡水庫周邊水域底棲動物優(yōu)勢種為橢圓蘿b螺Radixswinhoei、劃蝽Sigradistanei及霍甫水絲蚓Limnodrilushofmeisteri。秋季紅旗泡水庫及周邊水域底棲動物的密度分別為(150.44-152.88)ind·m和(229.334-192.89)ind·m。紅旗泡水庫的Magalef豐富度指數(shù)、Shannon—wiener多樣性指數(shù)及Simpson多樣性指數(shù)均低于周邊水域,而
3、Pielou均勻度指數(shù)高于周邊水域,說明紅旗泡水庫的底棲動物生物多樣性低于周邊水域,但均勻度較高。紅旗泡水庫底棲動物功能攝食群主要是雜食者,而周邊水域主要是捕食者。關(guān)鍵詞:紅旗泡水庫;底棲動物;群落結(jié)構(gòu);生物多樣_l生;功能群中圖分類號:X824文獻(xiàn)標(biāo)志碼:ACommunityStructureofMacrobenthosinHongqipaoReservoirandAroundingWatersinFallCAIYan,CHENFei,LIUMan.hongLIUMao—qi(1.NortheastForestryUniversity,Harbin150040,Chin
