摘　　要：为摸清贵州省不同区域农用地产能总量及其空间分布状况,提高贵州省不同区域农用地综合生产能力,根据贵州省农用地（耕地）产能核算的技术路线和方法,从农用地的理论产能、可实现产能和实际产能3个方面对贵州省农用地综合生产能力进行了研究。结果表明：贵州省农用地可实现单产为理论单产的66.18%,实际单产为可实现单产的47.49%;贵州省农用地理论产能利用强度平均为66.18%,可实现产能的利用强度平均为47.49%;农用地理论产能的利用潜力平均为3335.66kg/hm2,可实现产能的利用潜力平均为3428.2kg/hm2,大部分县（市、区）的可实现利用潜力为2000~5000kg/hm2;贵州省农用地理论产能利用潜力较大的地区有黔西南州、六盘水市和毕节地区;农用地可实现产能利用潜力较大的地区有铜仁地区、黔东南州、黔南州、遵义市、贵阳市和安顺市。The comprehensive productivity of arable land was studied from three aspects of theoretical productivity,realizable productivity and actual productivity according to the technical path and method of arable land productivity calculation to know gross productivity and spatial distribution of arable land in different areas for enhancing comprehensive productivity of arable land in different areas of Guizhou province.The results showed that the realizable per unit yield of arable land is 66.18% of the theoretical per unit yield,the actual per unit yield is 47.49% of the realizable per unit yield,the mean utilization rate of theoretical productivity and realizable productivity is 66.18% and 47.49% respectively,the mean utilization potential of theoretical productivity and realizable productivity is 3 335.66 kg/hm2 and 3 428.2 kg/hm2,the realizable utilization potential of most counties is 2 000~5 000 kg/hm2,Qianxinan prefecture,Liupanshui city and Bijie prefecture are of higher utilization potential of arable land theoretical productivity and Tongren prefecture,Qiandongnan prefecture,and Qiannan prefecture,Zunyi city,Guiyang city and Anshun city are of higher utilization potential of arable land realizable productivity in Guizhou.
