The demonstration effects and potential problems of Chinese marine eco-city on environment, energy and planning

Under the background of ocean and land-sea coordinated development, more than one-third coastal cities in China are proactively developing marine eco-cities, which makes demonstration effects in land-sea environment optimization, energy utilization and spatial planning. However, marine eco-cities are still facing some potential problems such as the conflicts between land ecosystem optimization and ocean ecosystem protection, the relationship of energy utilization structure optimization and efficiency improvement, the coordination between eco-city spatial planning and local government system, etc. These problems will be paid more attention to in the development of Chinese marine eco-cities in the future.
