Abstract: Based on the information about the Yellow River Delta wetland and socio-economic and natural environment obtained from on-site field tests, remote sensing image interpretation, literature and so on, this paper selected 26 diagnostic indicators for the wetland health to construct the index system to diagnose the ecosystem health of the Yellow River Delta wetland by the fuzzy comprehensive evaluation model. It showed that the whole Yellow River Delta wetland ecosystem was in a sub-health state caused not only by new land increase, serious soil salinization, the Yellow River swing and other natural factors, but also by irrational development of wetland, environmental pollution and other human factors, which had practical significance for wetland management and future research. We should protect and develop the Yellow River Delta wetland rationally.
