摘  要：
东寨港海草种类主要有2科2属3种,分别是单脉二药草Halodule uninervis、卵叶喜盐草Halophila ovalis以及贝克喜盐草Halophila beccarii,卵叶喜盐草与贝克喜盐草为东寨港优势种。东寨港海草资源面积约264.00 hm~2,平均盖度在52.13%,平均密度9 901.00株/m~2,平均生物量37.46 g/m~2。东寨港内海草资源处于退化状态,主要受底质类型、水环境、潮汐汊道、渔业活动、陆源污染、非法渔业以及自然因素等影响。通过对东寨港海草分布特征及变化分析,提高公众对潟湖海草保护意识,为海南岛潟湖海草床的保护与修复提供科学依据。

摘  要：
2 families, 2 genera and 3 species of seagrasses were found in Dongzhai Harbour, they are Halodule uninervis, Halophila ovalis, and Halophila beccari. And the dominant species were Halophila ovalis and Halophila beccari. An area of approximately 264.00 hm~2 Seagrass resources were found in Dongzhai Harbour, with an average coverage of 52.13 %, an average density of 9 901.00 plants/m~2, an average biomass of 37.46 g/m~2. According to the analysis, the seagrass resources in Dongzhai Harbour have been in a degraded state, mainly due to the influence of sediment types, water environment, tidal bays, fishery activities, land-based pollution, illegal fishing and natural factors. This paper hopes to improve the public awareness of seagrass protection in the lagoon by exploring the distribution patterns and changes of seagrass in the Dongzhai harbour, and to provide a scientific and theoretical basis for the protection and restoration of seagrass beds in the lagoon of Hainan Island.
