Abstract: Against the backdrop of significant coal resources being identified, the strategic layout of the coal power industry moving north and west has broken the original industrial structure of the eastern grassland region. The construction and operation of large coal power bases has provided reliable energy security for the eastern region, but it has also caused varying degrees of damage to the regional ecological environment, leading to a disruption of the regional carbon stability state. For this reason, effective measures should be taken to develop the coal power industry at the same time. It is particularly important to carry out ecological restoration and protection in parallel with the development of the coal power industry. Based on the system theory, this paper treats the ecology of the coal power base as a unified system, analyzes the interplay of ecological elements, proposes a system restoration framework to improve the ecological restoration effect through an integrated ecological restoration technology system according to the ecological environment characteristics of the coal power base in the eastern grassland region and the requirements of regional carbon emission reduction. Based on the system theory, this paper treats the ecology of coal power bases as a unified system, analyses the interactions of ecological elements, proposes a system restoration framework to improve the ecological restoration effect by integrating ecological restoration technology system according to the ecological environment characteristics of coal power bases in the eastern grassland region and the requirements of regional carbon emission reduction; constructs an evaluation index system for the ecological restoration effect of large coal power bases, and uses modern spatial information technology as a means to objectively evaluate the ecological restoration results of coal power bases by applying the fuzzy comprehensive evaluation method, so as to provide a reliable basis for reasonably delineating the spatial and temporal areas of ecological restoration and management of coal power bases, optimizing the ecological restoration mode and strengthening the control of the ecological restoration process. It promotes the collaborative development of large coal power bases in the eastern grassland region and enhances the ability to guarantee regional energy security.
