A Pressure-State-Response (PSR) framework was developed to realize a holistic health assessment of the Ulansuhai Lake in the Inner Mongolia. A total of 25 indicators including ecological character indicators, ecological function indicators and social environment indicators were organized to assess the lake ecosystem health. The Ulansuhai Lake was regionalized into three sub-regions (I, II, and III) in the consideration of ecological and environmental characters the lake. Results indicate the lake is in the state of Alert or Worse. The comprehensive health indices (CHI) of three sub-regions are 0.346, 0.385, and 0.445, respectively, reflecting obvious regional differences in ecosystem health of the lake. The current study may provide useful information for valid wetland restoration and management
