Core Viewpoint - The article highlights the significant growth of China's marine economy, projected to exceed 10 trillion yuan in 2024, emphasizing the harmonious coexistence of economic development and ecological protection in marine industries [1][12]. Marine Economy Development - China's marine economy is experiencing robust growth across various sectors, including marine fisheries, manufacturing, services, and emerging industries, contributing significantly to national economic growth [1][12]. - In Hainan, the marine production value is expected to grow by 10.4% in 2024, accounting for 34.1% of the regional GDP, driven by technological and industrial innovation [12]. Innovative Agricultural Practices - The cultivation of salt-tolerant crops, such as "sea worm grass," in saline-alkali land demonstrates an innovative approach to utilizing coastal areas for agriculture, promoting both economic and ecological benefits [2][5]. - The economic value of sea worm grass is substantial, with stable income of approximately 50,000 yuan per acre, while also contributing to environmental restoration by filtering nutrients from aquaculture [2][5]. Marine Engineering Materials - Research on long-lasting engineering materials is crucial for marine activities facing harsh conditions, with a new national laboratory established to address material corrosion issues that result in significant global economic losses [6][8]. - The laboratory aims to develop materials that can withstand the unique challenges of tropical marine environments, enhancing the durability of marine equipment [6][8]. Ecological Restoration Efforts - The Hainan Dongzhai Port National Nature Reserve, the largest mangrove area in China, is undergoing comprehensive ecological restoration, balancing protection and development [8][9]. - Increased public awareness and community involvement have led to improved biodiversity, with the number of bird species in the reserve rising from 185 to 230, indicating successful ecological recovery [9].
