摘要
根据1987年2、5、8和11月九龙江口红树林海岸潮间带生态调查资料,研究了多毛类的生态种类组成、数量分布与季节变化等生态特点。共鉴定多毛类41种,以近岸广盐性种类为主:平均栖息密度和生物量分别为54个/m^2和2.379/m^2,数量分布很不均匀,季节变化明显。盐度、沉积物和潮汐是影响本区多毛类生态特征的主要环境因素。
Based on the data obtained from the mangrove regions in the Jiulong River estuary in four months of 1987,the ecological characteristics of the composition,distribution and seasonal variation of Polychaeta in the area were studied.Forty-one species,mainly neritic euryhaline species,were identified.The average density and biomass were 54 ind./m2 and 2.37g/m2 respectively.The density and biomass were extremely uneven in distribution and clear in seasonal variation.Of the oceanog-raphic conditions which influenced the ecological characteristics of Polychaeta,salinity,sediment and tide were principle factors.
