深圳河口泥滩多毛类动物的生态研究

Studies on polychaete ecology on the mudflat of the intertidal zone in Shenzhen Estuary

１９９６年在深圳河口潮间带泥滩的４个季度调查共获得多毛类动物１６种。与大亚湾大鹏澳软相潮间带和九龙江口海岸潮间带多毛类相比，深圳河口潮间带泥滩多毛类种类较少，但密度和生物量较高，这与底质、有机质含量、红树林碎屑等有关。潮汐对深圳河口潮间带泥滩多毛类垂直分布的影响不明显。一些多毛类动物密度和生物量的水平分布与盐度有关。

Sixteen species of polychaete were got from the intertidal mudflat in Shenzhen Estuary in 1996 during four surveys.Compared with the polychaete at Dapengao in Daya Bay and in Jiulong Estuary,the average density and biomass of polychaete in Shenzhen Estuary were higher than in Daya Bay and Jiulong Estuary,which were related to the sediment,organic content and mangrove detrius.The tides effect on the vertical distribution of polychaete was not obvious. Salinity is a limited factor to the horizontal distribution of the density and biomass for some polychaeta.
