To address the unmet transportation demands for raw materials and finished products at the Taizhou Bay New Materials Industrial Park,a multi-scheme comparative study for adding new port shoreline in the waters near the Toumen port area is conducted.In response to national policies on reclamation control and ecological protection,the “permeable structures + sea-crossing approach bridge” model is adopted to arrange the port operation zone.This approach avoids reclamation projects and minimizes ecological disturbance.Focusing on the additional shoreline planning study for the Toumen port area of Taizhou Port,Que'er'ao Island is identified as the optimal site location based on a comprehensive analysis of factors including the natural shoreline condition,water depth,sheltering conditions,land depth,and ecological costs.A layout incorporating 32 berths is planned.At the same time,it is proposed to establish supporting systems for dust control,wastewater treatment,hazardous waste management,and oil spill emergency response,aiming to achieve green development throughout the entire port life cycle.The planning scheme of additional port shoreline in Toumen port area of Taizhou Port can efficiently support the logistics needs of the port-proximate industries,promote the construction of a world-class chemical new materials industry cluster in Taizhou,and provide a model for planning eco-friendly ports.
