Assessment of the integrated ecosystem in a mining area is one of the means of managing and regulating it. This paper studies the implications of the integrated ecosystem in mining areas, analyzes its characteristics and explains the emergy methods used to assess the ecosystem. The emergy evaluation indicator system for the ecosystem and its subsystem is discussed in further detail. Beizao coal mine in the Longkou mining area in Shandong province is taken as the research subject for an empirical study. Original data is employed to measure and calculate the separate emergy evaluation indicators for the years from 2006 to 2012. The results show that emergy theory and emergy analysis are effective methods to evaluate integrated ecosystems in mining areas and the change trends in the system reflected by each indicator. Excessive depreciation of nonrenewable coal resources, and low utilization ratio of renewable resources are typical characteristics for the integrated ecosystem in mining areas. The results show that the environmental burden is light. The research findings will offer researched support and the basis for making strategic decisions related to integrated ecosystem management in mining areas.
