| 摘 要： | 首次建立了黄河口邻近海域4个站位底栖动物生物量粒径谱和标准化生物量粒径谱。生物量粒径谱模式为三峰模式,3峰分别由海洋线虫,其他小型底栖动物类群和大型底栖动物形成。研究站位标准化粒径谱斜率变化范围为-0.859至-0.664,截距为15.035至16.331,与东、黄海和南黄海研究结果一致,可有效地指示营养输入状况和总生物量。同时,需要指出的是截距对总生物量的指示作用需注意粒级选择的一致性。利用粒径谱方法计算了底栖动物次级生产力,结果显示,研究站位平均次级生产力为6.717 g.DW.m-2a-1,大型底栖动物次级生产力为4.509 g.DW.m-2a-1,小型底栖动物次级生产力为2.208 g.DW.m-2a-1。粒径谱方法计算结果与其他次级生产力计算方法基本一致。与其他方法相比,该方法更加简便,可避免因对生物特性的把握不准而引起的计算误差。

| Abstract: | Biomass size spectra of benthic organisms(BBS) and normalized biomass size spectra(NBBS) were constructed for the first time in four stations in Huanghe River adjacent waters.BBS found in this study displayed the characteristic meiofauna-macrofauna trough and also showed bimodality within meiofauna size ranges,which was usually due to free living marine nematode and other meiofauna groups.The distribution of normalized biomass by size was linear(log2-log2 scale) at all stations.The slope of the NBSS ranged ... |
