摘要
于2010年6月对大连市旅顺口区南部基岩海岸潮间带大型底栖动物的种类、生物量、栖息密度进行了调查,对生物多样性和次级生产力进行了计算。调查结果表明,调查区域大型底栖动物20种,其中腔肠动物1种,环节动物1种,软体动物13种,节肢动物5种。大型底栖动物的平均生物量为4312.5g/m2,平均栖息密度为2966个/m2。调查区域的群落结构较为简单,但次级生产力水平高,营养结构较稳定。
The species number,biomass and density of macrobenthos were surveyed in rocky intertidal zones in south Lvshun,Dalian,Liaoning province,on June in 2010,and the biodiversity and secondary productivity were calculated.A total of 20 species was found,including 1 species of coelenterate,1 species annelid,13 species mollusks,and 5 species arthropods.There was average macrobenthos biomass of 4312.5 g/m2 in the rocky intertidal zones,with average density of 2966 ind/m2.The calculation of biodiversity and secondary productivity revealed that the community structure was simple,and showed the high secondary productivity and the stable trophic structure.
