| 摘要 | An ecosystem comprises an ecological community and it energetic and material interactions with the nonliving atmosphere, hydrosphere, and lithosphere. Ecosystems are both conceptual and functional units. The scale of concern is more manageable than that of the global ecosphere, yet higher than just that of the ecological community or population in that it more explicitly considers the physical influences on the biotic community. Research in ecosystem ecology is largely in the areas of energy flow—or trophic-dynamics—and biogeochemical cycling, and ranges from mesocosms to whole system manipulation experiments. Through integrated environmental assessment and adaptive management, the human factor has been brought more directly into ecosystem studies, including focus on urban ecosystems and urban metabolism. The ecosystem approach has been implemented recently for environmental management and conservation in notable national and global treaties. |
