| 摘 要： | 于2011-2013年5月和10月在厦门五缘湾海域设置7个站位进行大型底栖动物调查,并结合2005年的历史数据,运用AMBI和M-AMBI指数法评价该海域海底生态环境质量的时空变化状况。2011-2013年共鉴定大型底栖动物9门106科193种,多毛类(83种)、甲壳类(53种)和软体动物(25种)是该海域的主要优势类群,平均总密度和湿质量生物量分别为(518±292)ind/m2和(54.8±88.9)g/m2。多毛类的短鳃树蛰虫(Pista brevibranchia)为该海域的绝对优势种,其平均密度可达(170±179)ind/m2,其他优势种还有似蛰虫(Amaeana trilobata)、西方似蛰虫(Amaeana occidentalis)、丝鳃稚齿虫(Prionospio malmgreni)、梳鳃虫(Terebellides stroemii)、独毛虫属一种(Tharyxsp.)、菲律宾蛤仔(Ruditapes philippinarum)、长指马尔他钩虾(Melita longidactyla)和伍氏蝼蛄虾(Austinogebia wuhsienweni)等。评价结果显示,该海域底栖生态系统受轻度干扰,生态环境质量介于一般—优良之间,与2005年的调查相比,2011-2013年该海域的生态环境质量有所好转,这可能与五缘湾及周边海域近年来进行的海堤开口改造、海洋环境整治,以及海湾纳潮量及水交换能力的改善有关。

| Abstract: | Six surveys were conducted during 2011-2013 to assess the benthic ecological status of the stressed Wuyuan Bay (Xiamen, China) by the AZTI'S Marine Biotic Index (AMBI) and multivariate-AMBI (M-AMBI). A total of 193 species of macrobenthos were identified, which were belonged to 9 phyla and 106 families. The dominated ones were polychaetes, crustaceans and mollusks, which have 83, 53, and 25 species, respectively. The dominant species of polychaetes were Pista brevibranchia, Ruditapes philippinarum, Tharyx sp., Amaeana trilobata, Prionospio malmgreni, Terebellides stroemii, Melita longidactyla, Austinogebia wuhsienweni and Amaeana occidentalis. The average density and biomass (mean ± SD across all stations) of the total macrobenthos were (518±292) ind/m2 and (54.8±88.9) g/m2, respectively. The results showed that most sampling stations were slightly disturbed, and the benthic ecological status of Wuyuan Bay were between "moderate" and "good". Compared with the results of 2005, the average taxa numbers, the average density, biodiversity and M-AMBI values in the stressed Wuyuan Bay were increased, which might benefit from the uncork rebuilt of Wuyuan and Gaoji Causeway, treatment of marine environmental and improvement of water exchange in Wuyuan Bay and Xiamen area. |
