Abstract:

The wetland ecosystem is very complex, which has many characteristics and functions, such as integration, ecology, service, self- maintenance and autoregulation. Based on the ecological complexity theory, the paper analyses the wetland characteristics of Hutuo river from Gangnan reservoir to Huangbizhuang reservoir, and constructs the evaluation system and the standards of the health ranks to diagnose and evaluate the wetland ecosystem health from four aspects: structure, state, function and coordination with the fuzzy comprehensive evaluation model. The result shows that the wetland is in sub- health.

Key words: ecological complexity, ecosystem, health evaluation, Hutuo river, wetland
