广西涠洲岛跨海联网工程：“蛟龙”穿海不扰珊瑚

Core Viewpoint - The cross-sea interconnection project of the Southern Power Grid in Guangxi has successfully maintained environmental standards during its construction, ensuring minimal impact on the marine ecosystem [1][3]. Group 1: Project Overview - The cross-sea interconnection project is the first 220 kV cross-sea interconnection project in the Beibu Gulf, with a total investment of approximately 858 million RMB [1]. - The project involves laying 44.8 kilometers of submarine cables, which is considered the most complex and critical part of the construction [1]. Group 2: Environmental Monitoring and Impact - During the construction, the marine environment monitoring team reported that the water quality remained at Class I standards, with turbidity and chlorophyll concentrations within normal fluctuation ranges [1][4]. - The construction utilized advanced techniques such as multi-beam sonar and directional drilling to minimize seabed disturbance by 85% compared to traditional methods [3][4]. - The concentration of suspended solids in the water was maintained between 10 mg/L and 20 mg/L, which is considered safe for marine life [4]. Group 3: Ecological Compensation Measures - The project has implemented an ecological compensation plan with an investment in the tens of millions, releasing 37 million units of fish, shrimp, and shellfish for resource restoration [5]. - Continuous monitoring and protection of the marine environment are part of the project, establishing a benchmark for integrated ecological compensation in China [5].
