擦亮蔚蓝！山东河口北部海岸带生态修复项目通过竣工验收

Core Viewpoint - The ecological protection and restoration project in the northern coastal area of Dongying, Shandong Province, has been completed, contributing to the implementation of national strategies for ecological protection and high-quality development in the Yellow River basin [1][3]. Project Overview - The project is located in the Dongying District of the Yellow River Delta and includes various ecological restoration activities such as enhancing slopes over 6,322 meters, constructing live oyster reefs covering approximately 457.5 hectares, and restoring saline-alkali land over 120 hectares [3]. - The project aims to address ecological crises in the coastal area, including the invasion of invasive species and increased salinization, which threaten local biodiversity [3]. Key Strategies Employed - Eradication of Invasive Species: The project utilized a combination of methods such as cutting, tilling, flooding, and manual removal to eliminate invasive species, with a monitoring period of two years to prevent regrowth [3]. - Barrier Construction: New dikes were constructed using earth compaction and concrete reinforcement, while innovative oyster reefs were created to protect against wave erosion and provide habitats for marine life [5]. - Planting of Saline-Tolerant Vegetation: The project involved the use of drones and manual methods to plant salt-tolerant plants, which help reduce soil salinity and improve fertility for other plant species [7]. - Restoration of Natural Habitats: The project removed artificial aquaculture structures to restore natural marine ecosystems, promoting sustainable use of marine resources [9]. - Oyster Cultivation: A rapid construction technique for live oyster reefs was developed, utilizing local materials to enhance the ecological restoration of oyster habitats [11]. Environmental Impact - Upon completion, the project is expected to improve over 6 kilometers of coastal ecological environment, optimizing habitat conditions for marine life and supporting the recovery of the coastal marine ecosystem [13].
