| 中文摘要: |
| 为了解宁波大榭岛潮间带春季大型底栖动物群落结构与数量分布,探讨自然环境因子和人类活动对潮间带大型底栖动物种类组成及数量分布的影响,于2006年4月对大榭岛北岸岩礁相和泥沙相两种不同底质的潮间带大型底栖动物进行采样分析。研究表明:(1)岩礁相断面和泥沙相断面共发现大型底栖动物39种,其中贝类20种,多毛类8种,甲壳类8种;(2)岩礁相断面19种,主要以贝类生物为主,达16种,甲壳类只有2种;泥沙相断面20种,贝类、多毛类和甲壳类分布较为均匀,分别为4种、6种和8种;(3)岩礁相断面和泥沙相断面平均栖息密度分别为583.33 ind/m2和32 ind/m2,平均生物量分别为638.56 g/m2和7.83 g/m2,岩礁相断面栖息密度和生物量均远高于泥沙相断面;(4)岩礁相断面大型底栖动物群落垂直变化较泥沙相断面显著。 |

| In order to understand the distribution characteristics of macrozoobenthos in a intertidal zone,Daxie Island,and to reveal the influence of natural environment and human activities on macrozoobenthos community,field investigation of macrozoobenthos was carried out including a rock intertidal section(C1) and a tide flat section(C2) in Daxie Island,Apr.,2006.Main result showed that:(1) a total of 19 macrozoobenthos species were obtained in the section C1,most of which belonged to mollusks(16 species);a total of 20 macrozoobenthos species were obtained in the section C2,4 species of which belonged to mollusks,6 species belonged to Polychaeta,and 8 species belonged to Arthropoda;(2) the density and biomass in section C1 were 583.33 ind/m2 and 638.56 g/m2 respectively which are apparently higher than those in section C2(32 ind/m2 and 7.83 g/m2 respectively);(3) there were a stronger vertical variations of macrozoobenthos community in section C1 than in section C2. |
