根据2009―2010年在青岛汇泉湾潮间带开展的大型底栖动物调查,对不同季节不同断面的大型底栖动物的丰度和生物量进行了研究。结果表明,丰度和生物量的变化在时间上是持续降低的,而在空间上的变化无明显规律。在空间上,汇泉湾潮间带大型底栖动物的生境随经纬度的变化不大,底质环境是影响大型底栖动物分布的重要因素。不同的底质栖息的软体动物种类、生物量和栖息密度有较大差异。汇泉湾底栖生物群落的分布同沉积类型密切相关。

Based on macrobenthos survey carried out on different sections in four seasons form year 2009 to 2010 in the intertidal zone in Huiquan Bay,macrobenthos abundance and biomass were studied.The results show that the abundance and biomass of macrobenthos is a continuous decrease from spring to winter,but no significant change happens to spatial variation in same season.As to space,the changes in latitude and longitude of intertidal macrobenthic habitats in Huiquan Bay are not that large.Environment of flour is anther important factor that effects the distribution of macrobenthos.In different types of intertidal macrobenthic habitats,biomass and abundance are quite different.And the distribution of benthic communities is closely related with the sedimentary types.
