1、應用生態(tài)學報2010年7月第21卷第7期ChineseJournalofAppliedEcology,Ju.l2010,21(7):1844-1850太湖金墅灣水源地浮游植物群落結(jié)構*及其與環(huán)境因子的關系1,211**1,21,21,2李欽欽鄧建才胡維平胡柳明高峰朱金格12(中國科學院南京地理與湖泊研究所湖泊與環(huán)境國家重點實驗室,南京210008;中國科學院研究生院,北京100049)摘要利用典范相關分析方法(CCA),對太湖金墅灣水源地水體浮游植物群落結(jié)構及其與環(huán)境因子之間的關系進行了研究.共鑒定浮游植物7門58屬,群落組成以藍藻、硅藻和綠藻為主;4-14夏季浮游植物的種類和數(shù)量均較多,平
2、均密度為250@10ind#L,略高于春季(238@10ind#-1L).春、夏2季浮游植物群落結(jié)構差異較大,春季以藍藻為最優(yōu)勢門類、魚腥藻為最優(yōu)勢類群;夏季以綠藻為最優(yōu)勢門類,無最優(yōu)勢類群,但平裂面藻和柵藻在數(shù)量上較占優(yōu)勢.除受季節(jié)溫度影響外,春季影響浮游植物分布的主要環(huán)境因子依次為銨態(tài)氮、總磷、總氮和磷酸鹽,而總氮、銨態(tài)氮、磷酸鹽、懸浮物、高等水生植物、總磷和透明度對夏季浮游植物分布的影響較大.關鍵詞水源地浮游植物環(huán)境因子典范對應分析文章編號1001-9332(2010)07-1844-07中圖分類號X171文獻標識碼ACommunitystructureofphytoplanktona
