Evolution Characteristics of Land-sea Coordination Under High-intensity Development in Taizhou Coastal Zone, China

  • Land-sea coordination is a crucial strategy for ensuring the sustainable and rapid development of coastal cities. Assessing the level of land-sea coordination is vital for understanding the degree of coordination and identifying imbalances within land-sea systems. However, empirical research in this area remains scarce, necessitating further investigation. Using coastline, land use, and socio-economic data for the Taizhou coastal zone of China across seven time periods from 1990 to 2021, this study analyzed the spatiotemporal characteristics of coastal zone development intensity, developed a comprehensive evaluation model for land-sea coordination, and examined its evolutionary dynamics. The results indicated a substantial rise in development intensity within the Taizhou coastal zone, accompanied by significant alterations in coastline morphology and structure. These changes included a marked reduction in the extent of natural coastline and a corresponding expansion of artificial coastline. The intensity of coastal land use also increased, primarily driven by the expansion of built-up areas and aquaculture ponds. The development level of land-sea systems, as well as the overall coordination of the Taizhou land-sea system, demonstrated a consistent upward trend, advancing from basic to intermediate coordination. These findings provide actionable insights for enhancing land-sea coordination strategies to support the sustainable development of coastal cities.
