在2008 ~ 2012年的雨季和旱季，利用148种最常见的藻类，对海南岛三亚湾鹿头礁水花带和潮间带的海洋大型植物藻类和蓝藻进行了区系研究。从溅滩区到低潮间带，大藻多样性增加，蓝藻多样性减少。在中上潮间带，优势种（主要是高产的短暂生物）每年变化频繁。在低潮间带，优势种（以一年生肉质、叶状和皮质型为主）也发生了变化。旱季的物种数量比雨季多33%。雨季时，水花区以蓝藻为主，绿藻和红藻为主，从潮间带上游向低潮间带呈递增趋势。在旱季，飞溅区没有所有的大型藻类，只有一种蓝藻存活下来。潮间带上层以蓝藻和红藻为主，中低带以红藻和绿藻最丰富。尽管三亚湾污染严重，但物种数量和组成没有明显变化，海洋植物区系与印度洋-太平洋未污染地区相似。
A floristic study of marine macrophytic algae and Cyanobacteria in the splash and intertidal zones at Luhuitou reef, Sanya Bay, Hainan Island, China, was conducted during the rainy and dry seasons of 2008−2012 utilizing 148 of the most common species. Macrophytic algal diversity increased from the splash zone to the low intertidal zone, while cyanobacterial diversity decreased. In the upper and middle intertidal zones, the dominant species (primarily highly productive ephemerals) changed frequently throughout each year. In the low intertidal zone, the dominant species (mainly annual fleshy, foliose and coriaceous forms) also changed. In the dry season, species numbers were 33% higher than in the rainy season. During the rainy season, Cyanobacteria dominated the splash zone, while green and red algae dominated in increasing numbers from the upper to the low intertidal zones. During the dry season the splash zone was devoid of all macrophytic algae, and only one species of Cyanobacteria survived. In the upper intertidal, Cyanobacteria and red algae prevailed, while in the mid and low zones, red and green algae were the most diverse. In spite of heavy pollution in Sanya Bay, there was no evidence of dramatic changes in species numbers or composition, and the marine flora was similar to that of unpolluted regions in the Indo-Pacific.
