Study on the Construction of Zhanjiang-Haikou Railway under the Background of Hainan Free Trade Port

As Hainan Free Trade Port is about to launch the customs closure operation, the role of railway construction in building a high-level open economic system has become increasingly prominent. Based on a systematic analysis of the significance and value of the Zhanjiang-Haikou Railway construction, this study, through literature retrieval and field research, identifies the practical difficulties in the project construction as follows: complex geographical environment leading to significant engineering and technical challenges; cross-regional policy coordination and benefit distribution issues; and the balance between ecological protection and project construction. The feasible solutions proposed include: integrating multi-source data to construct a 3D geological-geophysical model; strengthening top-level design and providing legislative guarantees; and prioritizing ecological protection while promoting coordinated ecological restoration. This study is expected to provide theoretical and practical support for relevant work.
