| 根据２００４－２０１０年７个航次（每年８月初至９月上旬）共２００个站位的黄河口附近海域生态调查资料，研究其夏季浮游植物种类组成、丰度、优势种类和多样性指数的时空变化。结果表明，夏季黄河口海域共出现浮游植物１３７种，丰度变化范围为（７１．５１～２２９６．３１）×１０４个／ｍ３，优势种类历年变化较大，出现频率较高的优势种为中肋骨条藻（Ｓｋｅｌｅｔｏｎｅｍａｃｏｓｔａｔｕｍ）、垂缘角毛藻（Ｃｈａｅｔｏｃｅｒｏｓｌａｃｉｎｉｏｓｕｓ）、劳氏角毛藻（Ｃｈａｅｔｏｃｅｒｏｓｌｏｒｅｎｚｉａｎｕｓ）和菱形海线藻（Ｔｈａｌａｓｓｉｏｎｅｍａｎｉｔｚｓｃｈｉｏｉｄｅｓ）；多样性指数值远岸区域普遍高于近岸区域，低值区多数位于入海的河口附近。聚类结果显示，调查区域大致可分为３个浮游植物群落。 |
| 英文摘要: |
| Investigations，which included 7 voyages and 200 positions，were made every summer from 2004 to 2010. According to the investigated materials，this paper studied the phytoplankton's specific composition ，the abundance， the dominant species and the temporal and spatial variation of diversity index. The result showed that a total of 137 phytoplankton species were collected，the range of abundance was from 71.51 x 104 ind/m3 to2 296. 31 x 104 ind/m3.The composition of dominant species greatly changed，while higher frequency dominant species were Skeletonema costatum，Chaetoceros Laciniosus，Chaetoceros Lorenzianus and Thalassionema nitzschioide. The diversity index showed an upward trend from near coast to off coast，and the most low value areas were near the estuary. The clustering result showed that the phytoplankton community could be divided into three groups. |
