【摘要】 以文献资料和定性调查结果 ,综合分析了黄河三角洲附近海域浮游植物物种多样性 ;以 1 996年定量调查资料 ,研究了浮游植物多样度以及与均度、单纯度之间的关系。结果表明 :该海域共鉴定出浮游植物 72种 ,占本海域已记录浮游植物 1 1 6种 (变种 )的 62 % ,分占中国海和渤海已记录种类的 5%和 1 9% ;浮游植物多样度在 0 1 9～ 2 1 0之间 ,均度在 0 2 7～ 0 97之间 ,单纯度在 0 1 4～ 0 91之间 ;多样度与均度呈显著的正相关 ,与单纯度呈显著的负相关。更多还原

【Abstract】 Species diversity of phytoplankton in the sea near the Yellow River Delta has been analysed syntheticaly with the relevant references and the qualitative investigation results, and the diversity degree of phytoplankton and it’s relationship with evenness and simplicity have been also studied with the quantitative investigation materials got in 1996. The results obtained areas follows. 72 species of phytoplankton have been identified in this investigation, taking up 62% of 116 species of phytoplankton already recorded. They account for 5% and 19% of the species recorded in the China Sea and the Bohai Sea respectively. Phytoplankton diversity degree was between 0 19 and 2 10, evenness between 0 27 and 0 97 and simplicity between 0 14 and 0 91. Diversity and evenness were apparently positive dependent, but diversity and simplicity were negative dependent.更多还原
