Current situation of health evaluation of ecological system

An analysis was performed on some concepts related to ecological environment, ecological system, and the health of ecological system at present, and the process of research on the health of ecological system and some issues on the problems were reviewed. Two methods mainly used for evaluation of the health of ecological system were introduced, i.e. the indicator species method and index system method, and the advantages and disadvantages of the two methods were analyzed. In consideration of the factor that the health evaluation of ecological environment was mainly performed for single ecological system, it was proposed that a river basin should be taken as the basic element for health evaluation of ecological system.
