The coordinated development of land and sea is a guiding strategy for the development path and model of China's characteristic ocean. The dual attributes of land and sea in the coastal zone determine its inherent connection of mutual support and interactive cycle between land and sea. It is the core area and important carrier of coordinated development of land and sea. At the same time, the relationship between human activities and various factors such as land and sea resources and environment in the human sea system depends on the carrying capacity and the coordinated relationship between the elements of the land sea system. This study further emphasizes the role of the ocean from the perspective of the integration of land and sea space, taking into account its economic, ecological, and social functions. Under the integrated carrying concept of the "natural social economic status" of the land sea system, the study re examines the carrying capacity of the coastal zone. At the theoretical level, it explores the carrying mechanism of the multidimensional attribute fusion framework under the coordinated development of land and sea in coastal areas. At the practical level, it selects typical coastal areas in China based on multidimensional spatial functional units to scientifically measure and evaluate the carrying capacity status of the land sea multidimensional attribute fusion framework, and then analyzes its driving factors and mechanisms of change, in order to accurately grasp the construction of dynamic regulation of land sea coordination under high-intensity natural and human activity disturbances, Provide reference for optimizing and improving regional sustainability based on diversified development strategies.
