【摘要】 于1984年4-11月在莱州湾水域进行资源调查。分析表明,主要22种虾、蟹和头足类的捕获量为372400尾,8843kg；动物种类多样性H值为1．80－2．36。其中春季(5月)H值较高,为2．362夏季(8月)的为189；秋季(11月)的仅为1．80。显示种类多样性为中等偏低,种类群聚结构较简单。这3个季度月的种类多样性等值钱分布趋势是,莱州湾中部和黄河口北侧的H值,一般高于邻近水域。更多还原

【Abstract】 Trawl net samples collected from April to November in 1984 in Laizhou Bayyielded 22 species of main invertebrates, Crustacea and Mollusca among 372 400 in-dividuals totalling 8 843kg. The community species diversity index H was 1.80-2.36, being 2.36 in May, 1.89 in August and 1.80 in November which display thatspecies diversity was medium and community structure rather simple.The distribution of seasonal species diversity H isopleths of May, August andNovember showed that the centra water region of Laizhou Bay and the northernside of the Yellow River mouth are higher than that in adjacent waters.更多还原
