水质.海洋软体底栖动物的定量采样和样本处理指南 - The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay , estuary of dagu river , culturing and nearby area in hangdao in mar . , jun . , aug . and dec . , 2002 . abundance and biomass of macrofauna were investigated by quantitative study . the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分别在胶州湾北部软底区、大沽河口、黄岛养殖区及养殖区邻域选取四个典型站位，于2002年3月、 6月、 8月和12月野外采样，对大型底栖动物进行了定量研究，采用多元统计方法分析了群落结构和生物多样性，探讨了底栖生物群落与环境因子的关系；用丰度和生物量比较曲线法分析大型底栖生物群落对自然和人为扰动产生的响应。 - Compared with the studies on macrofauna in bohai sea and southern yellow sea , the macrobenthic abundance and biomass in jiaozhou bay were less than those of two seas . but the macrobenthic secondary production in jiaozhou bay was more than that of the bohai sea . using the sieves with 0 . 5mm aperture mesh in sorting quantitative macrobenthic samples shows more advantages than that of using sieves with 1mm aperture mesh
本研究同时使用了1mm和0 . 5mm孔径的网筛进行大型底栖动物的分选，通过两种孔径网筛筛留大型底栖动物的种数、丰度和生物量比较，说明0 . 5mm孔径的网筛对大型底栖动物分选在种类和数量组成优于1mm孔径网筛，使群落结构更完整，样品代表性更高。
