摘要
西沙群岛为我国南海诸岛中最大的群岛,自然资源丰富,该群岛珊瑚礁是典型的大洋型珊瑚礁,代表着我国现存最古老最珍贵的珊瑚礁,具有不可估量的社会经济价值。建立西沙群岛珊瑚礁生态系统自然保护区对表明我国政府对西沙群岛主权的重视及充分行使我国对西沙群岛的主权具有重要意义。西沙群岛珊瑚礁生态系统虽然具备不断调节自身的能力,但面对人类活动及全球变暖的双重压力,其前景仍然堪忧,建立自然保护区应该被海洋管理部门提上日程。该群岛珊瑚礁生态系统海洋生物资源丰富,具备保护的物质基础,也有足够的面积能有效保护造礁石珊瑚的生长和发展。西沙珊瑚礁区域是我国沿海地区珊瑚礁生态系统的发源地,珊瑚礁系统最完整和完好,因此保护管理的难度相对其他地区和海域要小得多,可保护性高。
Xisha Islands, the largest archipelago in the islands of South China Sea, has abundant natural resources. The coral reefs on the Islands are typical oceanic and are the oldest and rarest ones in China. They have immeasurable social and economic values. The future of the coral reef ecosystems on the islands is worrying under the pressures from humankind activities and global warming, although they have a wide scale of self-adaptation abilities. So it should be now on the calendar of governmental agencies to build Xisha Islands Coral Reefs Natural Reserve. According to the investigation of coral reef ecosystems on Xisha Islands, it is suggested to establish physical reserve areas and protecting objects. Four sea areas, Lingyang Island, Guanghua Island, Zhongjian Island and Qilian Island, are drawn up as the core areas of Natural Reserve. Four relevant buffers are set up on the periphery of the core areas, because there are some scleractinia corals, soft corals and gorgonian distribution on the buffer areas. The main protecting objects include tropical traits, local corals and their habitats, the rare and endangered sea animals and their habitats, coral reef bio-diversities and the abundant landscapes and tourism resources.
