In recent years, wetland evaluation has become a hot topic in environment research. With the enrichment of research content and methods for wetland environmental quality assessment, various mathematical methods and models are widely used. In this paper, evaluation methods of water environment, soil and ecosystems in wetlands were summarized at home and abroad. The uncertainty model of water quality evaluation, the biological effect method of soil risk evaluation and the index evaluation method of ecosystem were mainly concluded. Aiming at the shortcomings in the current study, it is pointed out that in the future, the real-time monitoring data should be automatically obtained by combining remote sensing technology and geographic information system, the dynamic evaluation model of water environment should be optimized, the establishment of wetland soil quality standard should be strengthened, and the coupling of multiple evaluation methods and the optimization of evaluation model should be further studied.
