| 摘要: |
| 通过对我国沿海多次野外实地考查以及文献报道, 采用统计学的分析方法, 研究了马尾藻属海藻资源的物种构成和区系分布特征。结果表明, 马尾藻属种数在我国海域的水平分布呈现出北少南多的趋势, 黄、东海仅17种, 南海达到124种、占世界马尾藻总数的36.47%。其中, 黄海西区、东海西区、南海北区和南海南区种数及小区单一分布种类数分别为10、13、82和61种及2、3、52和42种。我国特有种类为64种、占世界尾藻总数的18.82%。在我国沿海马尾藻的垂直分布特征为: 高潮带2种, 低潮带91种, 潮下带78种。 |

| Abstract: |
| Based on the materials from some field investigations along China coasts by authors and the references referring to genus Sargassum from China seas, the study on its species diversity and distribution was conducted using method of statistical analysis. The results are listed as following. The southern region of China seas distributes more species than those of the northern ones. There are 17 species located in the Yellow to East seas. However, the number of species reported in South China Sea is 124, accounting for 36.47% total number of Sargassum worldwide. Among them, the Sargassum species number of single area of China at the four areas (Western Yellow Sea, Western East China Sea, Northern South China Sea and Southern South China Sea) are 10, 13, 82 and 61; 2, 3, 52 and 42, respectively. 64 species are endemic to China seas, up to 18.82% of the total number of Sargassum in the world. At the coastal tidal zones of China, 2 species grow at the high tidal zone, 91 species at the lower intertidal zone with 48 species limited at this habitat, and 78 species at the subtidal zone with 36 species limited. |
