我国现存单种连片面积最大的海草床生态修复持续推进 为了“海底草原”更繁茂（美丽中国）

Core Viewpoint - The article highlights the successful restoration and protection of the largest seagrass bed in China, located in Caofeidian, Tangshan, Hebei Province, as part of a broader initiative for marine ecological protection and restoration [1][6]. Group 1: Seagrass Bed Overview - The Caofeidian seagrass bed covers an area of 4,427 hectares, making it the largest contiguous seagrass bed in China [1]. - Seagrass beds, referred to as "underwater grasslands," play a crucial role in stabilizing seabed sediments and providing habitats for marine biodiversity [2]. Group 2: Restoration Efforts - Since 2019, the Hebei government has implemented a restoration project that includes cleaning up fishing nets and restricting fishing activities to minimize impacts on the seagrass bed [3]. - The restoration process involves both natural recovery and artificial planting, with techniques such as seed balling and transplanting being utilized [5]. Group 3: Monitoring and Results - The restoration project has led to an increase in the number of benthic species from 60 to 111, with a biodiversity index improvement of 42.3% [6]. - An intelligent monitoring system has been established to track various environmental parameters, ensuring ongoing protection and management of the seagrass bed [7]. Group 4: Future Plans - Hebei plans to enhance daily supervision and long-term management mechanisms, as well as conduct comprehensive evaluations of the seagrass bed's restoration effectiveness [8].
