    摘要:

    2005年11月(秋季)对位于黄河口的岔尖岛、大口河岛和望子岛三岛的高、中、低潮带(岔尖岛:C1、C2、C3;大口河岛D1、D2、D3;望子岛W1、W2、W3)所设的9个采样站进行大型底栖动物调查,分析所获得的样品。结果表明,本次秋季调查共采到大型底栖动物34种,其中多毛类种类最多,13种,软体动物11种,甲壳动物8种,其他类群2种;大型底栖动物总平均栖息密度为164ind./m2,总平均生物量为61.12g/m2;9个采样站底栖生物的种类组成和数量特征有较大差异,其中物种数最高的为D3站,最低的为C1站。黄河口潮间带大型底栖动物生态特征主要受底质、潮汐、季节和人为干扰等因素的影响。

    Abstract:

    Based on the samples collected from nine intertidal stations from Chajiandao, Dakouhedao and Wangzidao of the Yellow River Estuary in December 2005, the macrobenthos of the intertidal zone in the Yellow River Estuary is discussed. The result revealed that 34 species, including 13 polychate species, 11 mollusk species, 8 crustacean species, 1 nemertinean species and 1 fish species were found in the three localities. The average density of macrobenthos was 164 ind./m2, while the average biomass was 61.12 g/m2. The species composition and quantitative character among the nine stations were different. The species number was highest in station D3, and lowest in station C1. The macrobenthic community was affected by the substratum, tide, season and human activity.
