摘要 通过对广东、广西和海南3省区近海水域的现场调查,初步发现和掌握了华南沿海地区主要海草的分布、种类、生物量、生产力和所面临的主要威胁.海草床主要分布在广东的流沙湾、湛江东海岛和阳江海陵岛等,广西合浦和珍珠港海域,海南黎安港、新村湾、龙湾和三亚湾等,总面积约为2400hm2.海革的种类主要包括喜盐草(Halophila ovalis)、二药藻(Halodule uninervis)、贝克喜盐草(Halophila beccarii)、矮大叶藻(Zostera japonica)、海菖蒲(Enhalus acoroides)、泰来藻(Thalassia hemperichii)、川蔓藻(Ruppia maritime)和海神草(Cymodocea rotundata)等8种.这些海草具有较高的生产力和生物量.海革床生境受的威胁主要包括修建虾塘、海水养殖、围网捕鱼、毒虾、电虾、炸鱼、挖贝、耙螺、拖网、人为污染、开挖航道以及台风等.
