| 摘 要： | 于2016年3月至2017年2月在浙江北关港附近海域进行污损生物周年挂板试验，全年共记录大型污损生物9门44科53属59种，种类组成以近岸暖水种为主，属于典型的亚热带内湾型污损生物群落。固着生活类型的悬浮物食者是该海域污损生物群落的优势群体，群落最主要的优势种是网纹藤壶（Amphibalanus reticulates），其次为长鳃麦秆虫（Caprella equilibra）、中胚花筒螅（Ectopleura crocea）、太平洋侧花海葵（Anthopleura nigrescens）、廉形叶钩虾（Jassa falcata）和强壮藻钩虾（Stenothoe valida）等种类。该海域污损生物全年各月均有附着，6-10月板的覆盖面积均达100%，附着盛期为6-8月，月板、季板、半年板和年板的平均附着密度和生物量分别为（21 371±8 722） ind/m2和（1 667.5±506.0） g/m2，（31 605±17 671） ind/m2和（5 879.1±2 576.5） g/m2，（31 188±10 834） ind/m2和（13 989.6±4 755.4） g/m2，（18 425±5 757） ind/m2和（6 581.9±2 175.9） g/m2，其中夏季附着强度最高。污损生物群落个体间因栖息空间和食物竞争而存在着相互依存或互相制约的关系，又依照对环境的适应性而存在着一定的时空分布规律。分析表明，温度是决定污损生物地理分布的最主要环境因素；另外，盐度、水体透明度以及光照等自然环境也是影响污损生物附着的重要影响因素。

| Abstract: | An annual panel test on marine fouling was carried out from March 2016 to February 2017 in the Beiguan Port,China. 59 species of fouling organisms belonging to 53 genera, 44 families and 9 phyla were identified. The fouling organisms were mainly composed of coastal and warm water affinities and reflected distinct characteristics of subtropical embayments.Sessile suspension feeders constituted the main core of settlement for the fouling community. Amphibalanus reticulatus was the most dominant and representative species in the fouling community,and other major species included Caprella equilibra, Ectopleura crocea, Anthopleura nigrescens, Jassa falcate, Stenothoe valida and so on. The settlement of fouling organisms occurred throughout the year, and the area colonized by them reached 100% from June to October,moreover, from June to August, it is the peak time for marine fouling. The average density and biomass on the monthly, seasonal, semiannual and annual test panels were (21 371±8 722)ind/m2 and (1 667.5±506.0)g/m2,(31 605±17 671)ind/m2 and (5 879.1±2 576.5)g/m2,(31 188±10 834)ind/m2 and (13 989.6±4 755.4)g/m2,(18 425±5 757)ind/m2 and (6 581.9±2 175.9)g/m2, respectively, and the adhesive strength of the fouling organisms was highest in summer. The individuals in the fouling community showed a mutual dependence or constraint relationship due to competition for settlement space and food, and they exhibited a particular spatiotemporal distribution in accordance with adaptation to environment. Analysis shows that temperature was the most important environmental factor determining the geographic distribution of fouling organisms. natural environmental conditions(such as salinity, water transparency and light) are all important factors affecting the settlement of fouling organisms. |
