| 摘 要： | 根据1986、1998和2000年春季对山东半岛南部水域进行的底拖网调查资料，对渔业资源、优势种及多样性的年间变化，利用多元统计分析方法对渔业资源群落的空间分布特征进行了分析。结果表明，种类更替加快，优势度下降，多样性增加，从而使群落结构发生了较大的变化，演替加快。

| Abstract: | Based on the bottom trawl surveys in the waters off southern Shandong Peninsula in spring 1986, 1998
and 2000, the yearly variat ions of nekton, dominant species were analyzed. The mult ivariate gradient analysis
was used in the study of community characteristics. The result s indicate that the period of shifts of species was
reduced, the species dominance decreased and the diversity increased in the surveyed areas of the Yellow Sea.
Therefore, the community structure has greatly changed, and succession increased. |
