南麂列岛海域春秋季网采浮游植物群落结构特征
Community Structure of Phytoplankton Sampled by Nets in Nanj i Islands Sea Area in Spring and Autumn
摘要
Abstract
[Objective]This article studied the current status of phytoplankton community struc-tures in Nanji Islands,Zhejiang Province and its relationships with environmental factors,to provide scientific support for assessment on the situation and development trend of the ecologi-cal environment quality of this marine area.[Methods]The species composition,density,domi-nance indices,the Shannon-Weiner diversity and the index of nutritional status assessment were analyzed based on the survey data of 28 stations in Nanji Islands in November,2013 and May, 2014,respectively.[Results]The index of nutritional status assessment revealed that the majori-ty of the Nanji Islands sea area was in the condition of eutrophication.24 phytoplankton species were identified in the spring and 22 species in the autumn with diatom and dinoflagellate domi-nated in both seasons.In the spring,Noctilucas cintillans,Coscinodiscus sp.and Thalassiosira sp.were the dominant species,while Paralia sulcata dominated in the autumn.[Conclusion]The species composition of the phytoplankton in Nanj i Islands sea area has decreased significantly and the average abundance has increased,in com-parison with the previous reports.关键词
