摘要
This thesis uses PSR model as a basis for studying the response of indicators at different levels to various pressures on Northlake wetland ecosystem and selects the most prominent influencing factors to construct a scientific indicator evaluation system. The results of the study show that the Northlake wetland ecosystem is marginally healthy, as indicated by its comprehensive health evaluation index of 0.5822. And the indexes of its three subsystems, i.e. Pressure-State-Response, are respectively 0.631, 0.465 and 0.695, of which the index of the State is the lowest, implying that the Northlake wetland is in an unstable state and has a risk of the wetland degradation.
