【摘要】 本文根据1987年2、5、8、11月调查资料，研究了厦门港岩相潮间带多毛类的种类组成、种类与数量的垂直分布、季节变化，并与大亚湾多毛类生态进行比较。结果表明，调查区域有多毛类47种。平均栖息密度60个／m2，平均生物量1．78g／m2，潮汐作用影响多毛类的种数、密度、生物量的垂直分布。多毛类数量的季节变化不甚明显，但冬季的栖息密度和春季的生物量较高。更多还原

【Abstract】 Based on the investigation data obtained in four seasonal months of February, May, August and November in 1987,the species composition,seasonal variation and vertical distribution of species and number of polychaete at the intertidal rocky zone Xiamen Harbour are studied and compared ecologically with that in Daya Bay. The results show that 47 species are recorded with an average of 60 ind. /m2 and 1. 78 g/m2 in the area surveyed. It shows that tidal effects play an important role on the vertidal distribution of species number,density and biomass of polychaete. The seasonal variation is not distinct though there are higher density in winter and higher biomass in spring.更多还原
