南黄海辐射沙脊群浮游动物群落结构及季节变化
Community structure and seasonal variation of the zooplankton in the radial sand ridge group region of the southern Yellow Sea
摘要
Abstract
The seasonal investigation on zooplankton community in the radial sand ridge group region of the southern Yellow Sea was carried out in May(spring),August(summer),November(autumn)in 2010 and February(winter)in 2011.There were 42 species totally found in this area,and the ranking of number of species in each season was summer(30 species)>spring(25 species)>autumn(16 species)>winter(14 species).The annual average abundance and biomass were 70.03 ind·m-3 and 54 mg·m-3 ,and the ranking of seasonal value of abundance was spring (144.61 ind·m-3 )>winter(51.76 ind·m-3 )>autumn(46.28 ind·m-3 )>summer(37.47 ind·m-3 ),while the ranking of seasonal value of biomass was spring(72 mg·m-3 )>summer(56 mg·m-3 )>winter(55 mg·m-3 )>autumn(34 mg·m-3 ).The abundance and biomass did not show obvious regularity in spring,however,the abundance and biomass increased in the southeast in summer and in the northeast in autumn,and were evenly wddis-tribution in winter.The dominant species in the area were Labidoceraeuchaeta and Calanussinicus.L.euchaeta was the dominant species all over the four seasons with high abundance and widely distribution.The abundance of C. sinicus was the max proportion in spring,while reduced with increase of temperature of sea water,and it became the dominant species again in winter.The distribution of the diversity index H′of zooplankton was 1.70,with the maximum value in summer(2.43),the minimum value in winter(1.08),and spring(1.97)and autumn(1.31). Overall,the community of zooplanktons had a simple structure in the sea area.The seasonal varation of the community structure of zooplanktons in this sea area has the similar regularity with its adjacent sea area.关键词
