摘要

Although the development of energy and mineral resources strongly supports China's rapid industrialization and urbanization,it has led to a series of ecological and environmental problems.Strengthening the spatial regulation considering the ecological and envir-onmental protection on energy and mineral resource development areas is an important aspect of realizing China's sustainable develop-ment.In this study,we mapped,categorized,and analyzed the ecological cumulative effects of the Chinese 134 prefectural mining units based on the pressure-state-response model,which is demonstrated as impact of mining activities on ecological environment,ecological environmental fragility,and ecological function.This investigation developed a stress zoning typology of the mining units based on scores of three dimensions of the ecological cumulative effects and classified 134 prefectural mining units into eight types of stress zones.A series of regulation and policy suggestions have been proposed to different types of zones from three aspects:space control,in-tensity control,and development mode control.The application of this evaluation and spatial zoning system will contribute to the re-fined spatial management of China's mining areas.
