Abstract: Ecological evaluation on wetland is a basis for wetland landscape plannng,magage ment and conservation.Focused on the wetland function and vegetation,this paper presented a synthetic ecological evaluation system,which included three integrat ed indices,i.e.,wetland’s ecological evaluation factors.These indices were grad ed and weighed by using the Analytic Hierarchy Process(AHP),and the composite ev aluation indices(CEI) were calculated.According to CEI,typical wtlands i n Jilin Province were classified into three different ecological types,i.e.,wetl and with normal ecolocial environment (CEI >0 7),wetland with critical ecol o cial environment(0 5< CEI ≤0 7),and wetland with extremely critical ecolog ical environment(CEI ≥0 5abstractIt was proved that the eco environment of wetla nd in the western Jilin Province was weak,and eco service function was very sen sitive.A basic idea of compatible development and exploration with environment p rotection was proposed.
