| 摘要: |
| 本研究旨在查明广东珠海唐家湾贝克喜盐草(Halophila beccarii)海草床的分布现状、退化趋势及其主要威胁因素，并提出科学可行的保护对策。通过在2024年8月至2025年10月期间开展的7次实地调查，对研究区域海草分布面积、盖度及人为干扰情况进行系统记录和探讨。调查发现，截至2025年10月，研究区域海草总分布面积仅存约0.051 hm2,较历史最大值(7.6 hm2,2008年)缩减超过99%；平均盖度为7.29%，呈现高度碎片化和低盖度特征。高强度赶海/渔业活动、人工沙滩修建及极端天气是海草床持续退化的关键影响因素，建议通过设立保护区，加强长期监测、公众教育与生态修复等措施来遏制海草床进一步退化，防止其在该区域功能性灭绝。 |

| Abstract: |
| The purpose of this study is to identify the distribution status,degradation trend and main threat factors of seagrass bed of Halophila beccarii in Tangjiawan,Zhuhai,Guangdong Province,and to propose scientific and feasible conservation countermeasures.Through seven field surveys conducted from August 2024 to October 2025,the distribution area,coverage and human disturbance of seagrass in the study area were systematically recorded and discussed.The survey found that as of October 2025,the total distribution area of seagrass in the study area was only about 0.051 hm2,which was more than 99% lower than the historical maximum (7.6 hm2,2008). The average coverage was 7.29%,showing characteristics of high fragmentation and low coverage. Intensive tidal flat harvesting and fishery activities,artificial beach construction,and extreme weather are the key driving factors for its continuous degradation. It is recommended to adopt comprehensive measures including establishing protected areas,strengthening long-term monitoring,promoting public education and conducting ecological restoration,so as to curb the further degradation of seagrass beds and prevent their functional extinction in this region. |
