摘要: |
利用2003年8月至2004年5月(夏、秋、冬、春季)4 个季度月在胶州湾辛岛潮间带的3个不同潮区的调查资料进行分析。结果共获得大型底栖动物43种,其中低潮区出现27种,中潮区和高潮区20种和19种,有 6种属于3个潮区共有种。大型底栖动物总平均栖息密度为102.5个/m2,5月最高,为144.67个/m2,2月最低,为52.66个/m2;总平均 生物量为60.01g/m2,11月最高,为102.99g/m2,2月最低,仅为11.87g/m2。本区大型底栖动物的栖息密度和生物量有明显的季节 变化。 |

The ecology of the macrobenthic community in the intertidal zone of Xindao, Jiaozhou Bay |
|
Abstract: |
Three sampling sites within intertidal zones of Xindao, Jiaozhou Bay, Shandong Peninsula, were set up to explore the community of macrobenthos during August 2003 to May 2004. Fourty-three species were found in the intertidal zones, of which 27 distributed in low tidal zone(X3), 20 in medium tidal zone(X2) and 19 in high tidal zone(X1), and only 6 species are common in the three tidal zones.The total average density of benthos is 102.5 ind./m2, the highest in May, 144.67 ind./m2, the lowest in February, 52.66 ind./m2; while the total average biomass is 60.01g/m2, the highest in November, 102.99 g/m2, the lowest in February, 11.87 g/m2. Meanwhile, the density and biomass are evidently different within four seasons. |
