| 摘要: |
| 为调查辽宁省黄海沿岸人工岸线上潮间带大型海藻多样性情况, 于2011 年10 月至2012 年6 月在大连湾、獐子岛、旅顺及丹东进行采样, 并与其附近天然岸线上海藻进行对比。调查结果显示, 在人工岸线上共发现17 种海藻, 以红藻与绿藻为主, 其中11 种可在相邻天然岸线发现。海藻多样性天然岸线＞混合岸线＞人工岸线, 但人工岸线上绿藻种类与天然岸线上的基本相同。在大连湾及獐子岛地区, 无机氮低的海域, 海藻多样性高; pH 高的海域, 海藻多样性高。调查中发现有人工岸线与天然岸线共存的混合岸线, 此岸线可看作是生境岸线(living shoreline)的一个变形, 为生物保护及生态恢复提供了新思路。 |

| Investigation of artificial shoreline seaweed along the Yellow Sea coast in Liaoning Province |

| Abstract: |
| To investigate the diversity of the benthic marine algae along the artificial shoreline of the Yellow Sea coast in Liaoning Province, we have investigated the seaweed species on the artificial shoreline at Dalian Bay, Zhangzi Island, Lvshun and Dandong from October 2011 to June 2012, and we compared them with the species on the nearby natural shoreline. Total of 17 species of marine algae were found on the artificial shoreline, and most of them were red and green algae, 11 species of them can be found from the nearby natural shoreline. The order of the diversity is: the natural shoreline＞hybrid shoreline＞artificial shoreline. The number of green algae on the artificial shoreline was almost the same as that on the natural shoreline. In the area of Dalian Bay and Zhangzi Island, the lower the concentration of inorganic nitrogen is, the higher the diversity of algae is; the higher the pH is, the higher the diversity of algae is. During this period, we found a hybrid shoreline where artificial shoreline can coexist with natural shoreline. This hybrid shoreline can be seen as a variant of the living shoreline. The hybrid shoreline provided a new thread to biological conservation and ecological restoration. |
