摘要2008 - 2012年，对海南岛海域7个采样点的藻类进行了采样。共收集到252个底栖大型藻类类群，其中53%为红色，31%为绿色，16%为棕色。种类最多的科是红藻科、Ceramiaceae、Cordophyaceae（红藻门）、刚毛藻科、石莼科、蕨藻科（绿藻门）、马尾藻科和网藻科（异鞭毛藻门）。2008-2012年期间对植物多样性和组成的分析显示，与珊瑚礁是主要生态系统的印度-太平洋热带地区其他大岛相似。通过对1990/1992年和2008-2012年藻类种类组成和形态多样性的比较分析，发现区系之间的最大相似性边界值分别为66%（Rh）、65%（Ch）和55%（Phaeophyceae，Ph）。这些十年的变化导致长寿命的体积形式的大型藻类的损失与细丝状藻类形式的数量增加，管状和叶片状的叶状体，海水污染和可能的自然灾害发生在1990年代和2000年代之间。
Abstract During the period from 2008 to 2012, algal samplings were conducted off Hainan Island (China) at seven localities. A total of 252 benthic macroalgal taxa were collected where 53% were reds, 31% greens and 16% browns. The largest numbers of species belonged to the families Rhodomelaceae, Ceramiaceae, Corallinaceae (Rhodophyta), Cladophoraceae, Ulvaceae, Caulerpaceae (Chlorophyta), Sargassaceae and Dictyotaceae (Heterokontophyta). The analysis of the floristic diversity and composition during 2008–2012 revealed similarity to that of other large islands in the tropical zone of the Indo-Pacific where coral reefs are the main ecosystem. As was shown by comparative analysis of algal species composition and form diversity between the periods of 1990/1992 and 2008–2012, maximum similarity boundary values between the floras amounted to 66% (Rh), 65% (Ch) and 55% (Phaeophyceae, Ph). These decadal changes resulted in the loss of long-living volumetric forms of macrophytic algae with an increase in the number of fine filamentous algal forms, with tubular and blade-like thalli, as seawater pollution and probably natural catastrophes occurred during the period between the 1990s and 2000s.
