Territorial spatial planning mediation of potential land utilization conflicts is a scientific choice to achieve regional high-quality development. It is of great significance to guide the national space utilization mode, space form and development direction with the value orientation of high-quality development. Taking the Yellow River Delta with equal emphasis on protection and development as an example, we established the conceptual framework and mathematical model of land utilization multifunctional potential conflicts based on social ecosystem theory and revealed the multifunctional potential conflict type, intensity and spatial pattern of land utilization based on ecological conservation, agricultural production and urban construction suitability evalu-ation. Next, the planning mechanism of "rigid constraint" and "flexible guidance" was used to mediate the po-tential conflicts of land utilization multifunctions, form the micropattern of Territorial spatial planning, and construct the Territorial spatial planning system for high-quality development according to the transmission path of multilevel spatial patterns. The results show that (1) the Yellow River Delta is characterized by the importance of ecological conservation, the suitability of agricultural production and urban construction, and it also presents the premise of the potential conflicts of multifunctional land utilization. (2) The multifunctional and potential conflict mediation process of land utilization in the Yellow River Delta presents obvious features of land-river-sea gradient differentiation, which reflects the optimal path of coordinated development trends of social ecosystems. (3) The multilayer transmission of the Territorial spatial planning pattern forms the grid-based constraint bottom line, the administrative main function area and the global national space protection and development strategic pattern, in turn, supporting the high-quality development of the region from the aspects of factor allocation, zoning control and strategic direction. (4) The Yellow River Delta as a whole is dominated by ecological con-servation and agricultural production patterns and has significant spatial agglomeration. The pattern of urban construction and elastic transition is relatively discrete. and multilevel Territorial spatial planning patterns for high-quality development have been developed. The Territorial spatial planning pattern of multilevel linkage constructs institutional control and spatial guarantees for high-quality development, and it is a scientific guide to regulate the harmonious coexistence of humans and nature in the Yellow River Delta.
