摘　　要：为了解椒江口多毛类时空分布特征,以及自然环境变化和工业污染对其的影响程度,于2007年10月、2008年1月、4月和7月在椒江口潮间带进行底栖多毛类和环境因子调查,分析了多毛类物种数、栖息密度和生物量的时空格局以及各断面水温、泥温、沉积物结构、盐度、滩涂宽度等环境因子对多毛类时空格局的影响。结果表明:(1)在所调查的6条断面4季共发现环节动物门多毛纲动物10科20种,以广温广布种为主;(2)季节变化明显,物种数、栖息密度和生物量在春季均最高(分别为13种,31.5ind/m2和0.58g/m2),秋、冬季次之,夏季最低(分别为4种,5.8ind/m2,0.21g/m2);(3)物种数呈现位于工业区附近断面低于下游较远处的断面的趋势;(4)沉积物结构、滩涂宽度对多毛类具有显著的影响,滩涂宽度较长、沉积物较细的断面种数、栖息密度和生物量较高。In order to understand the temporal and spatial variation of macrobenthic polychaetes, and the influence of natural environment change and industrial pollution on macrobenthic polychaetes in intertidal fiats, Jiaojiang Estuary, field investigation of macrobenthic polychaetes and environmental factors were carried out in October 2007, January, April and July 2008. The temporal and spatial variation of polychaetes （including species number, density, and biomass）, and the impact of some environmental factors （environmental temperature, sediment grain size, beach width, and salinity） on polychaetes were analyzed. The main results are as follows： （1） A total of 20 macrobenthic polychaetes species are obtained, most of which are eurythermal and widespread. （2） There is a distinct seasonal variations of species number, density, and biomass, the value of which are higher in spring （species number, density, and biomass are 13,31.5 ind/m^2 and 0.58 g/m^2, respectively） than that in any other seasons, while those in autumn and winter are in the next place, and in summer （species number, density, and biomass are 4,5.8 ind/m^2, and 0.21 g/m^2 respectively） are lowest. （3）The species number presents an ward trend from the sampling section near the industrial areas to that in the far downstream area. （4） Sediment grain size and beach width have a significant influence on macrobenthic polychaetes. Higher species number, density and biomass were found in the sections with wider beach and finer sediment.
