| 摘要: |
| 为明确海南澄迈花场湾环境因素对当地海草优势种贝克喜盐草(Halophila beccarii)的影响，本研究分别于2024年3月、6月、9月、12月对该区域进行4次野外调查及采样，分析贝克喜盐草的生长状况及其环境影响因素。结果表明，贝克喜盐草的形态和生理指标在月份间存在显著差异，海水温度及盐度、沉积物总磷(TP)及总铝(TAl)、沉积物间隙水可溶性磷酸盐(DIP)及总铝浓度是影响其生长的关键环境因素，适宜的温度和盐度有助于促进贝克喜盐草的生长，而沉积物中丰富的营养盐和铝元素对其形态和生理指标具有显著影响。未来还需在温度、pH值以及氮磷营养盐对贝克喜盐草影响机制方面开展深入研究，从而为海南贝克喜盐草海草床的保护以及修复提供数据支持。 |

| Abstract: |
| To clarify the effects of environmental influencing factors in Huachang Bay in Chengmai,Hainan Island on the local dominant seagrass species Halophila beccarii,this study conducted four times of field investigations and sampling in March,June,September,and December 2024 to analyze the growth status of H.beccarii and its environmental influencing factors.The results showed that there were significant differences in the morphological and physiological indicators of H.beccarii among months.The temperature and salinity of seawater, the Total Phosphorus (TP) and Total Aluminum (TAl) in sediments,and the Dissolved Inorganic Phosphorus (DIP) and TAl in sediment porewater were the key environmental factors affecting seagrass growth.Appropriate temperatures and salinity may facilitate the growth of H.beccarii,while the abundant nutrients and aluminum in the sediment can significantly impact morphological and physiological indicators of H.beccarii.In the future,it is urgent to conduct in-depth study on the influencing mechanisms of seawater temperature,pH value,and nitrogen and phosphorus nutrients on H.beccarii for the restoration and protection of damaged H.beccarii seagrass beds in Huachang Bay. |
