%X The study builds the diagnostic indicators of wetland ecosystem health, based on the characters of wetland ecosystem, according to the theories and approaches of the ecosystem health and the press-state-response model. The data used for the study include remote sensor data and statistic data. Many advanced technologies were adopted in this study, such as Remote Sensor (RS) and Geography Information System (GIS). Meanwhile, according to the assessment cell of small watershed, the study evaluates individual index and comprehensive index. By exploring the spatial distributing rules of wetland ecosystem health, following results were obtained: (1) In the structure of wetland ecosystem health of the Liaohe River Delta, better area accounts for 22%, generic area 52%, worse area 26%; (2) The health of Shuangtai National Nature Reserve is better, among this area in part of regions the situation of health is under threatening; (3) The main reasons, cause the damage to wetland ecosystem, are attributed to the reclamation of paddy field and the exploitation of oil.
