In order to study the effect analysis of resources, environment and ecological environment on ecological economy, the author proposes a method based on coupling model. Taking the relevant data of province A from 2001 to 2019 as the research basis, and screening indicators based on the response, state and driving force dimensions in the DPSIR model, construct the water environment DSR system and the economic DSR system, and obtain the comprehensive evaluation value and weight value of the system by means of the entropy weight method, the economic change and water environment assessment are briefly analyzed, and the coupling coordination degree of the two is discussed at the same time, and finally some suggestions for water environment optimization are put forward. Experimental results show that, the high-quality coupling degree of the total system cannot represent the content of the economic and water environment subsystems, and the collaborative goals, so it is necessary to conduct in-depth research on the degree of coordination. From the data in Table 4, it can be found that there is a significant difference in the degree of synergy between the two. Its synergy is in the range of 0.34799 to 0.93041, showing an upward trend year by year. It is proved that the coupled model can be used to analyze the effect of resources, environment, and ecological environment on the ecological economy.
