Distribution Characteristics and Conservation Recommendations for the Halophila beccarii Seagrass Bed in Tangjiawan,Zhuhai,Guangdong
摘要
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 sci-entific 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 sys-tematically 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 ex-treme weather are the key driving factors for its continuous degradation.It is recommended to adopt compre-hensive measures including establishing protected areas,strengthening long-term monitoring,promoting pub-lic education and conducting ecological restoration,so as to curb the further degradation of seagrass beds and prevent their functional extinction in this region.关键词
