From Shoreline to Sea: Evaluating Development Suitability Through Coastal Zoning and a Case Study from Shenzhen, China

Abstract

In Shenzhen, as a rapidly developing coastal city, balancing economic activities with ecological protection along the coastline posed significant challenges, particularly during urban expansion and infrastructure construction. This study analyzed coastline zoning, providing valuable lessons for other coastal cities and offering both theoretical and empirical support for more effective coastal management and sustainable development. The findings showed that the suitability zoning of coastlines revealed no clear spatial distribution trend, with most developed areas demonstrating high utilization efficiency, while unused coastlines had the potential for development. Targeted transformation and secondary development could improve resource efficiency while balancing economic and ecological needs. In conclusion, this research supported sustainable development in coastal cities and provided practical insights for others facing similar challenges in coastal management.
