1985年5—6月对黄河口及其邻近海域的27个站进行了大型底栖动物的首航次定量调查。分别对18种环境因子和68个优势种和习见种所做的聚类分析显示了黄河口水下三角洲与邻近海域的某些差异,并联系沉积环境将所研究海域划分为四个区:黄河口水下三角洲、莱州湾、渤海中部和渤海湾东部。对大型底栖动物与沉积速率的关系也做了初步探讨。
From May to June in 1985, the first metrological survey of macrobenthos was conducted on 27 stations in the Yellow River Mouth and its adjacent waters. The cluster analysis of 18 environmental factors and 68 dominant species and common species respectively showed some differences between the Yellow River Estuary and the adjacent sea areas and divided the study area into four areas according to the sedimentary environment: Lower Delta, Laizhou Bay, central Bohai Sea and eastern Bohai Bay. The relationship between macrobenthos and sedimentation rate was also discussed.
