Abstract

Seagrass beds are a type of coastal wetland with many ecosystem services and precious economic values. Seagrass meadows used to be widespread along the coasts in northern Chinese seas, yet they have long been overlooked and lack devoted study on their history and status. This paper firstly reveals, by synthesis of information on composition of seagrass species and their distribution, that the seagrasses in this region have experienced considerable declines, both in terms of distribution and biomass, from the earliest record to present days. Then, a case study at the seagrass bed of Chudao is described to show the status of representative seagrass meadows. The results indicate that the environmental condition is good, seagrasses are in recovery, the planktoners are healthy and rich fishery resources and the mammal finless porpoise are associated with the seagrass bed. The cause(s) of historical seagrass decline and current conditions are also discussed, and future recommendations on seagrass protection and mapping are suggested.

잘피밭은 많은 생태계서비스를 제공하는 경제적 가치가 매우 높은 연안습지의 한 종류다. 중국에서도 북부연안을 따라 넓은 잘피밭이 분포하나 오랫동안 중요성이 간과되어 왔고 연구도 부족한 실정이다. 본 논문은 최초로 중국 북부연안 잘피의 종류와 분포를 제시하였으며, 과거로부터 현재까지의 변동양상을 기술하여 역사적인 감소추세를 분포와 생물량의 관점에서 기술하였다. 대표적인 잘피밭의 현황을 나타내기 위해 추다오 지역을 선정하여 사례를 제시하였다. 환경조건이 좋은 곳에서는 잘피도 회복되고 있으며, 잘피밭에 의존하는 플랑크톤과 어류, 돌고래 등 해양포유류도 풍부하였다. 역사적인 감소추세와 현상황에 대한 원인이 토의되었으며 보호를 위하여 필요한 연구내용을 제시하였다.
