Coastal retreat line is an important part of coastal land spatial planning, which balances the needs of resource utilization and ecological protection of coastal cities, and ensures the safety bottom line of healthy and sustainable development of coastal areas. At present, China's coastal retreat line lacks a systematic evaluation and management and control system. By combing the correlation mechanism between five impact dimensions such as social economy value, spatial development potential, landscape style risk, marine disaster risk, and ecological environment value and various elements of the coastal zone, this paper established an evaluation system for the importance of coastal retreat line in coastal areas with land and sea planning, summarized the hierarchical, classified, and differentiated management and control strategies of coastal retreat line in China, and took Dongying City as an example. The paper further discussed the application of the evaluation system in the demarcation and control of retreat line, to provide a reference for the control of coastal land spatial planning.
