Abstract：The coordination of resource utilization in coal mining area is the basis for measuring the level of com-prehensive carrying capacity.[Objective]By studying the coordinated change trend of coal mining scale and wa-ter and land resources carrying capacity in Zezhou coal mining area,we can formulate corresponding countermea-sures to achieve coordinated utilization of resources.[Method]First of all,based on the natural coupling relation-ship between coal mining and water and land resources carrying capacity,the paper analyzed the damage of coal mining to water and land resources under the mode of synchronous utilization of resources;and then through the establishment of coal-land-water resources carrying capacity evaluation index system,quantitative analysis of resource utilization level;the structure coupling coordination model was used to analyze the coupling degree and the spatial distribution characteristics are analyzed by GIS.[Result]Time series results showed that in addition to the large scale of coal mining in 2011,the water and land resources carrying capacity was destroyed,the over-all coordination degree presented an increasing trend.From the perspective of spatial distribution,the three zones were distributed almost in the same phase. By analyzing the spatial distribution characteristics of coordination subarea,the following countermeasures were put forward:①The low coordination 1 zone contains 47 administra-tive villages,mainly distributed the border of the study area with small coal mining scale,the advantages of land resources carrying capacity should be brought into play,and the exploitation and utilization of mining land would be used to balance the needs of the coal industry and improve the coupling coordination degree;②The highly co-ordinated 3 zone was mainly located in the mining area,its coal mining scale was reasonable at present.For the rich water resources,we should pay attention to conserving water resources,saving water and reducing water pol-lution;③The moderate proportion of the 2 zone with the largest proportion was 53%,and the scale of coal min-ing was too large.The scale of coal mining should be rationally planned within the range of the carrying capacity of the resources,so as to make the three parties pay equal attention to each other and develop a harmonious and unified one.[Conclusion]The change of coal mining scale and its water and land resources carrying capacity gradually changes from disorder to order,and the three development is gradually coordinated.The development counter measures,based on the coordination and the partition of the space distribution characteristics,considered the resources development and utilization of the coordination development,can provide a scientific guarantee for sustainable development.
