Based on the survey of benthic algae in the intertidal zone of Ma' an Archipelago from March to July 2007, the algal species composition, distribution, and temperature feature were studied. The dominant algal species in the study area were preliminarily analyzed by using similarity indices (S(c)) and index of relative importance (IRI(c)). A total of 31 species sampled in sublittoral area were identified, among which, 7 species of 5 genera belonged to Chlorophyta, 8 species of 5 genera belonged to Phaeophyta, and 16 species of 14 genera belonged to Rhodophyta. Topical and selective distribution species influenced by wave and tide were identified in the intertidal zone. Ulva pertusa and Sargassum thunbergii were found in all survey area. Rhodophyta was the dominant species, with the occurring frequency being up to 61.1%, and Chlorophyta showed quite uniformed horizontal distribution. In addition, 81% of sampled species were from low-tide zone, and some were extended from mid-tide zone to low-tide zone. The composition comparability between mid-tide and low-tide species was 0.47, and the convergence effect in mid-tide and low-tide zone was higher than that in high-tide and mid-tide zone. The sublittoral area of Ma' an Archipelago showed obvious vertical zoning character, with temperate species being absolute abundant, and the warm-water species dominant. The marine floral texture of Ma' an Archipelago belongs to warm temperate-subtropical transitional marine flora.
基于2007年3月至7月对马鞍列岛潮间带底栖藻类的调查，研究了藻类的种类组成、分布及温度特征。利用相似性指数（S(c)）和相对重要性指数（IRI(c)）对研究区域内的优势藻类种类进行了初步分析。共鉴定出潮下带采样的31个物种，其中绿藻门5属7种，褐藻门5属8种，红藻门14属16种。在潮间带确定了受波浪和潮汐影响的局部性和选择性分布物种。在所有调查区域均发现了孔石莼和鼠尾藻。红藻为优势种，出现频率高达61.1%，绿藻水平分布较为均匀。此外，81%的采样物种来自低潮带，部分物种从中潮带延伸至低潮带。中潮带和低潮带物种的组成相似度为0.47，中潮带和低潮带的趋同效应高于高潮带和中潮带。马鞍列岛潮下带呈现明显的垂直分带特征，温带物种绝对丰富，暖水物种占优势。马鞍列岛的海洋植物区系属于暖温带-亚热带过渡性海洋植物区系。
