中文摘要：
于2012年11月18日至12月21日,在黄、东海沿从南向北（26~36°N）一个断面24个站采样调查了表层（4 m）砂壳纤毛虫群落。共发现砂壳纤毛虫17属,32种。各站砂壳纤毛虫种丰富度为2~15种,砂壳纤毛虫总丰度为2478~88550个/m3。整个断面优势种为筒状拟铃虫、白领细壳虫、小领细壳虫和钝囊坎虫。巴西拟铃虫仅出现在青岛近岸（24号站）,但丰度很高（10960个/m3）。砂壳纤毛虫种类多样性从南向北降低,从近岸向远岸增加,黏着壳的比例在近岸水浅处较多,在水深大于50 m 的站位,透明壳所占比例大大增加。不同种类的砂壳纤毛虫有着不同的分布区域,根据分布区域的不同,可分为南方种,北方种和广布种等。聚类分析结果显示,调查区的砂壳纤毛虫可以分为3个群落。
英文摘要：
The tintinnid species richness and abundance in surface waters （4 m depth） of Yellow Sea and East China Sea （26~36°N） were investigated at 24 stations during 18 November to 21 December in 2012. Totally 32 species in 17 genera were found. The species richness of tintinnids in each station ranged from 2 to 15. The tintinnid abundance ranged from 2 478 to 88 550 ind./m3. The dominant species included Tintinnopsis tubulosoides, Stenosemella nivalis, Stenosemella parvicollis and Ascampbelliella retusa. Tintinnopsis brasiliensis only appeared in station 24 but had a high abundance （10 960 ind./m3）. The tintinnid species richness decreased from south to north, increased from nearshore water to offshore area. The proportion of agglutinated loricae was much higher in shallow coastal water, while the proportion of hyaline loricae increased when the water depth was more than 50 m. Tintinnids could be divided into south species, north species and widespread species. Three communities were identified by cluster analysis.
