| 摘要: |
| 利用统计法、经验模型和多元聚类分析法和数学分析软件对2006 年12 月908 项目冬季航次山东南部海域(36°15′ —36°45′N, 120°45′—122°00′E)小型底栖生物调查所获得的数据进行分析,获得该调查海域冬季小型底栖生物的平均丰度为(657.43±214.60) ind/10 cm2, 平均生物量为(847.15±427.63) μgdwt/10 cm2, 平均生产量为(7624.32±3848.64)μgdwt/(10 cm2·a?1); 还对N/C、Simpson 优势度指数、Margalef 多样性指数、Pielou 均匀度指数和香农-威纳指数进行了计算。与2006年8 月908 项目夏季航次同一海域调查数据进行了比较, 得到小型底栖生物的平均丰度及其优势类群线虫丰度冬季明显低于夏季, 而生物量和类群多样性与夏季相当。同时, 依据丰度指标对山东南部研究海域进行了初步的生态学划分, 呈现出较明显的地域性。

| Abstract: |
| Some meiobenthos were obtained from the research region(36°15′—36°45′N, 120°45′—122°00′E)in December of 2006 and examined, from which eight ecological indexes of meiobenthos were set: abundance, biomass, productivity, N/C, Simpson index, Margalef index, Pielou evenness index, and Shannon-Weiner index. Analysis results were compared against the data of August 2006. A preliminary ecological division was made in mainly the abundance of meiofuanal taxa.
