Abstract: The basic concepts and their connotations of restoration ecology and its general situation of researches, as well as the objectives, principles, procedures and techniques of ecological restoration, were discussed in this paper. It is suggested that the restoration ecology research should give consideration both to the basic theories including the succession of ecosystem and its damage process and reaction mechanism under disturbance, and to the applied techniques, including the restoration of soil, water body, atmosphere and vegetation, the conservation of bio-diversity, and the assemblage and integration of ecosystem. The ecological restoration and reconstruction is a systematic engineering, which is in the light of ecological principles and by the certain biological, ecological and engineering techniques, to artificially control the key factors and processes of ecosystem degradation, and regulate and optimize the flow processes and their spatial and temporal sequences of matter, energy and information among the ecosystem and its environment, by the aim of successfully restoring the structure, function and ecological potentials of degraded ecosystem to their original or higher level.

Key words: Restoration ecology, Damaged ecosystem, Ecological engineering
