摘要
根据2006年8月～2007年10月对青岛南部近岸海域进行的4个航次的调查,探讨了该海域浮游桡足类群落特征及其与环境因子的关系。结果表明:调查海域共出现浮游桡足类27种,占浮游动物总种类的27.85%。其中秋季种类最多,达24种;夏、春季分别为17种、10种;冬季最少,为8种。桡足类丰度年平均值为60.32ind/m3,其中秋季最高,达122.47ind/m3;春、冬季分别为68.48ind/m3、28.41ind/m3;夏季最低,为21.91ind/m3。从水平分布上看,春季桡足类丰度西部明显大于东部;夏季却呈现东部大于西部的趋势;秋季则是从近岸向远岸递减;冬季总体分布规律不明显,除站位ZD-QD255较高外,其它站位丰度相对较低。香农-威纳指数、均匀度指数、丰富度指数的平均最大值都出现在秋季。香农-威纳指数、均匀度指数平均最低值出现在冬季,而丰富度指数平均最低值出现在春季。
Based on the data from investigations of coastal waters south of Qingdao from August 2006 to November 2007, community structure of copepods and their relationship to the environmental factors of the sea area were analyzed. Results showed that.. Total 27 species of planktonic copepods were identified, accounting for 27. 85% of zooplankton species. The numbers of copepods in spring, summer, autumn, winter were 8,17,10 and 24, respectively. The average abundance of the four seasons was 60. 32 ind/m3 , with the highest abundance in autumn （122.47 ind/ma） and the lowest in summer （21.91 ind/m3）. The horizontal distribution of copepods in the investigated area presented higher values in western area than eastern area in spring, while there was the opposite distribution in summer. The abundance in autumn gradually decreased from inshore to offshore. The abundance in winter was desultorily low, with an exceptive high abundance in station ZD-QD255. The maximums of Shannon-Wiener index, richness index and evenness index were observed in autumn. The dex existed in winter, while the minimum value of minimums of Shannon-Wiener index and evenness inrichness index appeared in spring.
