Abstract：The Xinjie Taigemiao mining area is located on the northeastern edge of the Mu Us Sandy Land.Under the dual influence of climate change and human activities,regional water resources are scarce,and the ecological carrying capacity is nearing its limit,while a large amount of mine drainage remains difficult to utilize effectively.In response to the above issues,the importance of balanced water resource allocation for the integration of blue-green spaces in semi-arid regions is analyzed.Combining regional geological and historical environmental changes,current physical geography,and expected mining subsidence,a fundamental framework for constructing regional blue-green spaces is proposed.Concurrently,through comprehensive research using remote sensing image analysis and statistical yearbook data,the elements and attribute characteristics of blue-green spaces under the regional sandy land-lake-grassland landscape pattern are systematically analyzed.Focusing on the quantity and quality characteristics of mine water and its comprehensive utilization potential,strategies for synergistic blue-green integration to achieve supply-demand balance and enhance ecosystem stability,as well as suggestions for optimizing spatial pattern zoning,are proposed.The aim is to progressively realize the protection and utilization of natural resources,improve the quality of urban and rural living environments,and ensure the safety and stability of the regional ecological pattern,thereby exploring and forming a new model for integrated ecological management and comprehensive resource utilization in semi-arid coal mining areas that aligns mining and land development.
