Ecosystem health refers to a state that is not affected by ecosystem stress syndrome, has resilience and self-sustaining ability, does not affect neighboring systems, is not affected by risk factors, is economically feasible, and maintains the health of human beings and other organic communities. Ecosystem health not only refers to ecological health, but also includes economic health and human health.
Ecosystem health assessment includes not only multi-scale ecological indicators reflecting the integrity, vitality and resilience of the ecosystem, such as system comprehensive level, community level, population and individual level, but also physical and chemical indicators, as well as socio-economic and human health indicators, reflecting the quality and sustainability of ecosystem services provided by the ecosystem to human society.
Ecosystem health is an important prerequisite for sustainable development, and only a healthy ecosystem can provide good ecosystem service functions for human beings. A healthy ecosystem is not only the material basis for human survival and development, but also the basis for human health.
It is an important task for future environmental workers and environmental management departments to maintain and maintain the sustainability of ecosystem structure and function, repair the trauma of ecosystem, rebuild the damaged earth life support system and realize the health of ecosystem.
