摘　　要：对土地资源生态承载力研究可反映出一个地区的绿色程度、人地协同程度。基于人地协同视角,运用DPSIR模型和障碍度模型对2005—2018年喀斯特山区贵州省土地资源生态承载力进行评价及障碍因素诊断。研究表明:(1)贵州省土地资源生态承载力总体呈上升态势,综合承载指数极差达128.46%。(2)2005—2018年贵州省土地资源生态承载力的驱动力指数、状态指数、响应指数总体皆为上升态势,压力指数、影响指数整体上表现出波动下降的变化趋势,揭示经济社会发展与土地资源生态环境承载力进一步协调,但还有一定的提升空间;压力指数、影响指数指标作为土地资源生态环境的直接反应成为影响贵州省土地资源生态承载力状态的主要障碍因素。(3)影响贵州省土地资源生态承载力的主要障碍因素为人口密度、常住总人口、人均绿地面积、碳排放总量、人均粮食产量。Research on the ecological carrying capacity of land resources can reflect the green degree of a region and the degree of human-land synergy.From the perspective of human-land synergy,the article uses the DPSIR model to evaluate the ecological carrying capacity of land resources and diagnose the obstacle factors in Karst mountainous areas of Guizhou Province from 2005 to 2018.The research results were presented as follows:(1)The overall ecological carrying capacity of land resources in Guizhou Province is on the rise,and the comprehensive carrying index is extremely poor by 128.46%;(2)From 2005 to 2018,the driving force index,status index,and response index of the ecological carrying capacity of land resources in Guizhou Province were all on the rise,and the pressure index and the impact index showed a trend of declining fluctuations as a whole.It reveals that economic and social development and the carrying capacity of land resources and ecological environment are further coordinated,but there is still room for improvement;The pressure index and impact index are the direct response to the ecological environment of land resources and become the main obstacles that affect the ecological carrying capacity of land resources in Guizhou Province.(3)The main obstacle indicators affecting the ecological carrying capacity of land resources in Guizhou Province are population density,total permanent population,per capita green space area,total carbon emissions,and per capita food production.
