青岛东风盐场东半区底栖动物种群的初步研究

COMPOSITION AND DISTRIBUTION OF MACROBENTHOS IN DONG FENG SALTERN OF QINGDAO

对青岛东风盐场东半区底栖动物的种类组成和数量分布进行了调查.共获得底栖动物28种,其中腔肠动物1种,多毛类8种,软体动物9种,甲壳动物7种,昆虫幼虫2种,鱼类1种;总平均生物量为68.47g/m^2;总栖息密度为5048个/m^2.生物量组成以软体动物为主要类群,占总生物量的50.9%.栖息密度组成以甲壳动物为优势类群,占95.33%;底栖动物分布不均,高生物量和高栖息密度均集中在2号站,且该站底栖动物种类也相对多样化.

In this paper dealt with are the investigative resules of the species composition and quantitative distribution of biomass and density of macrobenthos in the east half of Dong Feng Saltern of Qingdao. 28 species of macrobenthos were cellected at 3 stations. The biomass and density as well as the variation in the distribution of the main classifications are described and analysed.
