摘　　要：喀斯特地区土地贫瘠,土地有效利用面积比例小,土地资源生产潜力小,环境容量低,生态环境脆弱。文章从光合潜力、光温潜力、气候潜力和气候土地潜力等方面综合考虑建立土地生产潜力模型,对贵州清镇喀斯特溶原坝地生态重建示范区土地人口承载力的耕地承载力部分进行了估算研究。研究表明,仅从耕地人口承载力来看,该区目前尚有潜力可挖。Aiming at setting up a production potentiality model of this area, we have conducted an estimating investigation of the population carrying capacity of the cultivated land in Qinzhen pilot area, the typical karst mountain peaks and ground of Guizhou province, in consideration of four factors: 1)photosynthesis potentiality; 2)photosynthesis and temperature potentiality; 3)climate potentiality; 4)climate and soil potentiality. The investigation shows that the current total population does not exceed the population carrying capacity in this area, judging from the potential production capacity of the cultivated land.
