| 摘 要： | 珠江口海底管线、跨海大桥及港口码头堤坝等近岸海底工程构筑越来越多，为服务于当地的经济发展需要，广州海洋地质调查局使用数字测深仪、多波束水深测量系统和旁侧声纳扫描系统，对珠江口内伶仃岛以北水域(内伶仃洋)的水下地形地貌进行了调查。利用调查资料，分析了内伶仃洋的水下地形地貌特征，认为内伶仃洋水下格局总体上呈三滩两槽分布，发展趋势处于不断的淤浅和萎缩，但人为作用已对水下地形地貌产生了较大的影响，破坏了水下生态环境，应加强水域综合管理，加大环境保护力度。

| Abstract: | The Pearl River Estuary area has developed economy, large population and many factories.To meet the needs of development,more and more underwater engineering constructions for pipe lines, bridges and harbors get under way.Guangzhou Marine Geological Survey (GMGS) conducted topographic and geomorphologic surveys in 2003 by using digital echo sounding system, multi-beam system and side scan sonar system. According to the survey data, the author analyzed the underwater topographic and geomorphic features in inner Lingdingyang firth.Generally,the firth is characterized by three shoals with two channels in between, and they are getting shallow and shrinking continuously. The seafloor is greatly influenced by human,and the underwater environment is deteriorating. We must enhance comprehensive management and environmental protection. |
