This paper analyzes the coupling relationship and coupling factors between ecological landscape planning and architectural design, combines ecological planning with landscape planning and design and explores the practical value of green architecture. The ecological landscape construction is divided into five systems, and three indicators with a high degree of influence on the health of the urban ecosystem are selected as the system influence factors to construct a healthy coupling synergy model of ecological landscape planning and architectural design. Taking Fujian Province as an example, we analyze the degree of coupling between ecological landscape planning and architectural design systems and the regional distribution of the level of coupling coordination in Fujian Province. The highest coupling coordination degree between ecological landscape planning and architectural design is R10 and Rl for green buildings, with coupling coordination degrees of 0.8341 and 0.8001, respectively, and the lowest is R = 59 0.3854. Thus, it is important to synergize between architectural design and ecological landscape planning and construction.
