广州市城市规划勘测设计研究院有限公司开展海籍调查并绘制宗海图，明确隧道主体、附属设施及周边 海域的空间权属关系，实现"纵向分层、横向分界"的精准确权。 "这相当于为海底隧道发放了'立体身份证'。"南沙区分局不动产登记相关负责人介绍："海底隧道涉及航 道、渔业、生态等多重空间关系，分层确权能有效避免权属交叉和开发冲突。此举不仅提升了海域资源 利用效率，还为后续海底电缆管道、海上风电等项目的产权管理提供了借鉴。" 南沙区作为广东自贸试验区重要片区，近年来持续深化海洋领域"放管服"改革。此次海底隧道三维确权 将进一步推动海洋基础设施建设的规范化、市场化。下一步，南沙区将探索推广这一模式至海上光伏、 海洋牧场等新兴领域，助力构建"蓝色经济"生态圈。 近日，广州市南沙区成功办理全省首例海底隧道不动产确权登记。此次确权采用三维立体测绘技术，不 仅为海底隧道等复杂海洋工程的不动产登记提供了"南沙样板"，也为全省海洋空间资源的高效利用和权 益保障探索再添新成果。 位于粤港澳大湾区西岸的新建南沙至珠海（中山）城际万顷沙至兴中段项目用海横跨广州、中山两市， 用海类型为路桥用海，用海方式为海底隧道，用海空间层为底土，其中洪奇沥水道 ...
