摘　　要：1996年 1月至 1998年 12月在深圳河口潮间带泥滩获得多毛类 2 5种 ,隶属 15科 2 3属 .多毛类优势种为羽须鳃沙蚕 ( Dendronereis pinnaticirrus)、腺带刺沙蚕 ( N eanthes glandicincta)、尖刺缨虫( Potamilla acuminata)、独毛虫 ( Tharyx sp.)、寡鳃齿吻沙蚕 ( N ephtys oligobranchia)和小头虫( Capitella capitata) .A断面多毛类生物量的季节变化为每年 4月 (春季 )最高 ,10月 (秋季 )最低 ,RB断面的多毛类从 1996年 7月起 ,以及 ET断面的多毛类从 1997年 7月至 1998年 4月 ,均处于低密度和低生物量状态 .根据不同时间内多毛类优势种、密度和生物量的比较 ,判断了多毛类栖息环境受扰动状况 .A和 ET断面 1997年 10月至 1998年 10月、RB断面 1996年 7月至 1998年Twenty five species of polychaete belonging to 15 Families and 23 Genera were obtained from January 1996 to December 1998. The dominant species were Dendronereis pinnaticirrus, Neanthes glandicincta, Potamilla acuminata, Tharyx sp., Nephtys oligobranchia and Capitella capitata . The polychaete biomass at transect A were all the highest in spring (April) and the lowest in autumn (October) every year. The polychaete densities and biomass at transect RB were low from July 1996 to October 1998 and the polychaete densities and biomass at transect ET were low from July 1997 to April 1998. Polychaete living environment were assessed according to polychaete dominant species, densities, biomass in different sampling transects and seasons. The results showed that the polychaete at three transects were disturbed from July 1997 to July 1998.
