| 摘 要： | 1997－1998年在鸭绿江口设4个测站,双月1次捕取样品,进行鱼虾群落研究。渔获66种水生动物,其中鱼类48种、甲壳类11种、其他动物7种。出现频率最高的前5种为斑尾复虾虎鱼、拟棒鞭水虱、亚洲公鱼、脊尾白虾和纹缟虾虎鱼。数量比例最高的前5种优势种为拟棒鞭水虱（31．82％）、糠虾（25．44％）、中国毛虾（21．21％）、斑尾复虾虎鱼（17．35％）和亚洲公鱼（0．5％）。各站生物量指数和物种丰度分别变化于3．83－33139．59和0．34－2528．24。群落物种的多样性指数（H')变化于0．291－2．889。优势度指数（C1）0．155－0．914,均匀度指数（J')0．113－0．970。群落间相似性系数（Cs)2－3站最高（平均0．649）,1－4站最低（平均0．245）。群落物种种类和数量分布与季节和生态条件密切有关。

| Abstract: | From 1997 to 1998, the samples of fishes and shrimps were collected at 2-monthly intervals from 4 spots in the estuary of Yalu River (Liaoning Province). The total samples contained 66 species of aquatic animals, including 48 species of fishes, 11 species of crustacean and other 7 species. Among the surveys, 5 species, i.e. Synechogobius ommaturus, Cleantiella isopus, Hypomesus transpacificus nipponesis, Paraemon carinoicauda and Tridentiger trigonocephalus, appeared in the highest frequency. The dominant species in number were Cleantiella isopus (31.82%), Mysis sp.(25.44%), Acetes chinensis (21.21%), Synechogobius ommaturus (17.35%) and Hypomesus transpacificus mipponensis (0.5%), respectively. The biomass index and species abundance at each station varied from 3.83 to 33 139.59 and 0.34 to 2 528.24 respectively. The species diversity index within community changed from 0.291 to 2.889, the superiority index from 0.155 to 0.914 and the evenness index from 0.113 to 0.970. The similarity index between communities was the highest between station 2 and station 3 (mean 0.649) and the lowest appeared between station 1 and station 4 (0.245). The distribution of species and quantity of community were closely related to seasonal changes and ecological condition. |
