| 摘 要： | 在长江口北支北八滧河以北贝类放流滩涂湿地的潮下带水域,采集大型底栖动物,分析大型底栖动物群落在滩涂贝类放流前后的变化。贝类放流后在放流区邻近潮下带海域共采集到大型底栖动物51种,其中软体动物15种,节肢动物17种,环节动物4种,脊索动物14种,纽形动物1种,全年优势种有8种。年平均密度为0. 265个/m~2,年平均生物量为0. 06 g/m~2,年香农-威纳多样性指数为0. 93,年丰富度指数为0. 895,年均匀度指数为0. 39。与放流前调查的大型底栖动物群落相比,贝类的放流影响了放流区邻近海域的底栖动物群落和优势种的组成。

| Abstract: | Macrobenthos were collected in the subtidal waters of the wetland of the north branch of the Yangtze River estuary. The changes of macrobenthos community before and after the release of shellfish in the area were analyzed. A total of 51 species of macrobenthos were collected in the shellfish released area adjacent to the subtidal zone. There are 15 species of mollusks, 17 species of arthropods, 4 species of annelids, 14 species of chordates, and 1 species of nemertea. Eight dominant species were found throughout the year. The annual average density was 0.265 ind/m2, the annual average biomass was 0.06 g/m2, the annual Shannon-Wiener index was 0.93, the annual Margalef index was 0.895, the Pielou index was 0.39. Compared with the macrobenthic community before release, the release of shellfish affects the composition of benthic communities and dominant species in the adjacent waters of the released area. |
