Abstract:

研究了海南新村港、黎安港、文昌和琼海(潭门)等地的优势海草种类海菖蒲(〖WTBX〗Enhalusacoroides〖WTBZ〗)、海神草(〖WTBX〗Cymodocearotundata〖WTBZ〗)及泰来藻(〖WTBX〗Thalassiahemperichil〖WTBZ〗)中氮、磷及铁的含量和影响因素.研究结果表明,海南潮间带海草对养分的吸收与海水营养水平及沉积物氮、磷、有机碳、铁有关.相对于氮,海草叶片磷含量受海水和沉积物的影响更明显.海水磷、沉积物有机碳和铁均能促进海草组织对磷的吸收.海草叶片的氮磷比为新村港(21.73)>黎安(14.25)>文昌(9.53)≈潭门(10.29),与海水中溶解性总氮和溶解性无机磷的比值呈线性正相关,说明海水的富营养化影响了海草叶片的氮磷平衡.
