摘    要:为了解椒江口化工园区及其邻近区域潮间带大型底栖动物分布特征,评价工厂排污对河口潮间带大型底栖动物生态的影响范围及程度,在椒江口共设置6条潮间带采样断面,于2007年10月和2008年1月进行了大型底栖动物野外调查.研究结果如下:(1) 秋冬两季共采集到大型底栖动物75种,其中秋季64种,冬季29种;(2) 物种数呈现河口外断面高于河口内断面的变化趋势;(3) 在各断面软相基质站位,化工园区及其邻近区域的大型底栖动物物种组成差异较大,栖息密度和生物量差异不显著;(4) 与国内其他河口近几年的调查数据相比,椒江口潮间带发现的大型底栖动物种数较高,且存在开敞型河口潮间带大型底栖动物种数大于内湾河口潮间带的现象.

关 键 词:椒江口  化工园区  潮间带  大型底栖动物

Distribution characteristics of intertidal zone macrozoobenthos in autumn and winter in Chemical Industrial Park and adjacent area, Jiaojiang Estuary
Abstract:In order to assess the ecological impact of chemical discharges on intertidal macrozoobenthos, the community distribution of macrozoobenthos was investigated in intertidal zone of Chemical Industrial Park and adjacent area, Jiaojiang Estuary. Field sampling of macrozoobenthos was carried out including six intertidal sections in Oct. 2007 and Jan. 2008. The results showed that: (1) A total of 75 macrozoobenthos species were obtained, of which 64 species were found in autumn and 29 species in winter; (2) The distribution of macrozoobenthos species number showed an increasing trend from inner to outer estuary; (3) The macrozoobenthos species was significantly different in soft-intertidal zone between the Chemical Industrial Park and adjacent area, despite of similar biomass and density; (4) Compared with other estuaries in China, more macrozoobenthos species were found in Jiaojiang Estuary, which may be related with its wide estuarine gate geographically.
Keywords:Jiaojiang Estuary  Chemical Industrial Park  intertidal zone  macrozoobenthos
