Ecological technology model and path of seaport reclamation construction

Reclamation plays an important role in alleviating the contradiction between the supply and demand of land. But its environmental negative effect is also obviously. Considerable research has been conducted on the environmental impact assessments of reclamation activities, but few and scattered studies have focused on how to reduce the negative impacts of reclamation projects on coastal ecosystems. Therefore, this paper considered the ecological technology integration study of reclamation construction as the breakthrough point. China, which has the highest reclamation scale worldwide, was also selected as the main research area, and its representative seaports were selected as the subjects of the study. Then, questionnaire survey and literature analysis were conducted. The ecological technology model and path of the seaport reclamation construction were studied by focusing on port site selection, port plane layout, wharf structure and plane form. Construction material selection and ecological restoration construction projects were also investigated. The suggestions regarding scientific demonstration and planning of port site selection, ecological port plane design and structure, application and innovation of recycling economy technology, and active construction of ecological restoration engineering were provided. The purpose of this research is to determine the effective implementation of ecological and environmentally friendly reclamation under a reasonable management scale, thus providing a reference for establishing the ecological technology model of reclamation and promoting the effective protection and sustainable development of marine resources from the perspective of source planning and management.
