渤海湾“海底草原”生态修复再造“蓝碳”

Core Viewpoint - The article discusses the ecological restoration of the "seagrass meadow" in the Bohai Bay, highlighting its significance as a "blue carbon" ecosystem and its role in enhancing marine biodiversity and local economic development [1][3]. Group 1: Ecological Importance - The Caofeidian seagrass bed is the largest contiguous seagrass area in China, covering an area of 43.83 square kilometers [1]. - Seagrass meadows, which occupy only 0.1% of the ocean's area, account for approximately 18% of the total carbon sequestration in marine environments [1]. - The seagrass bed serves as a crucial habitat for various marine species, often referred to as the "nursery of the ocean," supporting regional marine biodiversity and fisheries [1]. Group 2: Restoration Efforts - Since 2019, restoration efforts have been initiated, combining natural recovery and artificial restoration techniques, leading to the development of a technical system for ecological restoration [3]. - As of now, 938 hectares of seagrass beds have been restored, with the number of large benthic species increasing from 60 to 111, resulting in a 42.3% improvement in biodiversity index [4]. - A smart monitoring system has been established to oversee the seagrass beds, providing real-time environmental data and enabling quick responses to any anomalies [4]. Group 3: Economic Impact - The ecological restoration has led to significant economic benefits, with the establishment of a "tourism+" development model that includes marine leisure fishing and educational tourism [4]. - In 2024, the Caofeidian area is projected to receive 8.99 million tourists, generating a total tourism revenue of 6.628 billion RMB [4]. - The region has been designated as an ecological protection red line, implementing stricter conservation measures to ensure the sustainability of the seagrass meadow [4].
