Multi-Level Comprehensive Assessment of Constructed Wetland Ecosystem Health: A Case Study of Cuihu Wetland in Beijing, China

Wetlands are one of the world’s three major ecosystems. They not only maintain regional ecological balance but also provide an important guarantee for human survival. Wetland ecosystem health assessment serves as foundation wetland protection, management, and restoration. In this study, method proposed by United States Environmental Protection Agency (US EPA) was selected improved to systematically evaluate status Cuihu wetlands’ at levels. The results revealed that landscape development intensity index 1.55, total pattern value 10 points, score rapid evaluation 0.79. Levels I II indicated in a good near-natural state. Additionally, level III is higher area B than A. wetlands were characterized low species diversity distribution benthic animals aquatic plants. comprehensive health. future, should be monitored regularly, cultivation propagation plants strengthened, effective methods improve water quality reduce soil salinity used achieve best wetlands.
