[Important ecological topics on regional scale ecosystem management in China].

Ecosystem management is a synthetic applied ecology concerning ecosystem management theories, practical technologies, relevant policies and management strategies. It is not only an urgent need for the sustainable development of human society, but also an important tendency and scientific task of ecosystem management to develop integrated studies on models of global or regional scale ecosystem management and the relevant scientific problems. For this reason, we systematically expounded a series of important ecological topics, such as the synthetic evaluation and ecological mechanism of the services, sustainability, complexity, and indeterminacy of ecosystem, the ecological basis of natural resources conservation, ecosystem health, and the rehabilitation of degraded ecosystem, basic ecological processes for ecosystem management, theories and practice on adaptive management of ecosystem, ecosystem network study, monitor, and achievement integration, as well as synthetic special topic studies on regional scale ecosystem management etc. Research advances and tendencies of these topics at home and abroad were also reviewed.
