Basic principles of restoration ecology and ecological engineering of degraded ecosystem

The major fields of restoration ecology such as the monitoring, simulation and prediction of ecosystem digression,key technologies of degraded ecosystem restoration, ecosystem structure and function optimalization, etc. are put forward. In addition,some principles of restoration ecology including the theories of disturbance control, ecosystem succession, inter-species relation, landscape structure and function are dealt with in this paper. Finally, some advices on how to apply these principles to degraded ecosystem are given.
