海南创新推行海域立体分层设权，解锁立体用海新模式

Core Viewpoint - Hainan is innovatively implementing a three-dimensional layered rights allocation for marine areas, transforming the traditional flat usage model into a more efficient and harmonious coexistence of various marine projects, thereby unlocking new dimensions for marine economic development [2][4]. Group 1: Innovative Marine Space Management - The new approach allows for the division of marine space into four layers: water surface, water body, seabed, and subsoil, enabling different projects to coexist without conflicts over space [4][5]. - The implementation of this layered rights allocation is seen as a necessary choice to improve resource utilization efficiency and resolve conflicts in marine usage [5][6]. Group 2: Practical Applications and Benefits - The first project under this new model is the Hainan seabed data center, which occupies only 14.46 hectares across three layers, leaving the seabed space available for other uses [3][7]. - Other projects, such as the cross-Ningyuan River connection and the municipal connection project in Sanya, have successfully utilized layered marine space, marking a significant advancement in marine management practices [7]. Group 3: Regulatory Framework and Future Directions - The new regulations, effective from May 1, provide a solid legal foundation for the layered rights allocation, promoting a shift from two-dimensional to three-dimensional marine management [5][6]. - Future plans include further research and the establishment of mechanisms for the exit of inefficient marine usage, aiming for sustainable development of marine resources [7].
