摘　　要：明晰喀斯特山区“三生”空间协调关系以及碳排放效应,有助于喀斯特山区城市绿色发展规划。运用耦合协调模型、转移矩阵探析铜仁市31年“三生”空间协调关系和演变特征;采用碳排放系数方法测算铜仁市20年“三生”空间碳排放量。结果表明:①1990-2020年,铜仁市县域“三生”空间呈现转型趋势,耦合协调关系也呈现出由西向东转移趋势。两两系统耦合值和耦合协调值呈现“生产-生态”>“生产-生活“>“生活-生态”的现象。②铜仁市生态用地转入趋向增加,转出趋向减少;生产用地转入趋向减少,转出趋向增加。③2000-2020年,铜仁市净碳排放由341.6119万t增长至1137.8190万t,年均增长37.91万t。研究结论可为喀斯特区域可持续发展提供科学依据。Clarifying the spatial coordination of the"production-living-ecological"(PLE)spaces in karst and the effect of carbon emissions can help the planning of green development in karst mountainous areas.The coupled coordination model and transfer matrix were used to analyze the spatial coordination relationship and evolution characteristics of the PLE spaces in Tongren City,and the carbon emission coefficient method was used to measure the spatial carbon emissions of the PLE spaces in Tongren City.The results show that:from 1990 to 2020,①the PLE spaces at the county level in Tongren City exhibit a transformation trend,with the coupling and coordination relationships also showing a shift from west to east in the counties of Tongren city.The coupling coordination value and coupling value of the two systems shows the phenomenon of"production-ecological">"production-living">“living-ecological;②in Tongren City,the conversion into ecological land shows an increasing trend,while the conversion out of ecological land is decreasing.Conversely,the conversion into production land is decreasing,while the conversion out of production land is increasing;③the net carbon emissions of Tongren City increased from 3,416,119,000 tons to 11,378,190,000 tons,with an average annual increase of 379,100 tons.The conclusions of the study provide scientific basis for the sustainable development of karst region.
