Ecological Status and Influencing Factors of the Dashentang Oyster Reef in Tianjin
摘要
Abstract
Oyster reefs are important coastal ecosystem,possessing high economic value and significant ecological service functions.The Dashentang oyster reef in Tianjin is recognized as the modern living oyster reef ecosystem with the highest latitude discovered so far in northern China.It plays an essential role in maintaining the ecological functions of the adjacent waters and contributes to the understanding of historical interactions between the sea and land in Bohai Bay.However,the current situation and the influencing factors of this typical ecosystem is insufficient studie and requires further investigation.A comprehensive survey focused on the oyster population,benthic biological community and environmental factors was conducted during 2021 to 2023.The current situation and influencing factors of the oyster ecosystem were analyzed in this study.The results indicated that the reef-building species in the Dashentang Oyster Reef is Crassostrea gigas,with a density ranging from 237 to 2 680 individuals per square meter.The benthic biological community within the ecosystem is relatively stable,and there is a large difference in the biodiversity index of benthic organisms inside and outside the reef area.The water environment is significantly affected by terrestrial inputs.During the study period,the overall density of oysters showed an upward trend,and the degradation trend has slowed down.Nevertheless,the oyster reef ecosystem is still affected by various human activities,including fishery harvesting,marine engineering construction,and terrestrial pollution,and its survival situation remains severe.Therefore,is recommended that relevant management departments strengthen maintenance and protection of the Dashentang oyster reef.关键词
