In recent years, various cities have continued to build urban landscapes with typical characteristics, but most of the urban landscape constructions are too similar. There is even a problem that the urban landscape is not recognised by the local people, and the same is true for the problem of ecological water governance. This article aims to study the sustainable innovation of urban landscape construction and ecological water environment governance process. To this end, this article proposes fuzzy comprehensive evaluation criteria and goals, through this evaluation system to evaluate the urban landscape construction and ecological water environment management process, and at the same time design experiments to investigate. The experimental results of this paper show that the evaluation system can help improve the urban landscape construction and ecological water environment management. At the same time, the analysis results show that under this evaluation system, urban residents’ satisfaction with the urban landscape has increased by 47 %. At the same time, the effect of water treatment has also been improved, with an improvement effect of 31 %. For the actual governance process, the effect is huge.
