摘　　要：为定量测算和分析湖北省区域节约用地情况,依照人均建设用地标准法,以2009年为基期年,通过限制性修正系数对理论潜力进行修正,估算了湖北省83个县(市、区)到2020年城乡建设用地置换潜力,并调查了各个县(市、区)规划期间闲置空闲与废弃地复垦潜力。研究结果表明:目前湖北省土地利用以粗放利用为主,限制性修正系数与地形地貌存在一致性,置换潜力与闲置空闲及工矿废弃地复垦潜力存在空间上的负相关性;到2020年湖北省共可节约土地25.24万hm2,其中城乡置换潜力占18.66万hm2,闲置空闲与工矿废弃地复垦潜力占6.58万hm2,今后全省建设用地利用的方向是以现有建设用地内部挖潜为主,且逐步控制城市建设用地与农村居民点用地无序蔓延。该文为今后制定土地利用规划、土地整理计划等提供决策依据。To quantitatively assess and analyze intensive land use potential on regional scale in Hubei province, according to per capita construction land standards, the potential use of urban-rural construction land was calculated with restrictive correction coefficients which amend to the theoretical potential and the amount of idle land and waste land was investigated for 83 counties of Hubei province from 2009 to 2020. Results showed that extensive use pattern still dominated intensive use pattern in Hubei province and the restrictive correction coefficients were consistent with the geographic and geomorphic conditions. At the same time, transposition potential was spatially negative correlated with potential from idle and waste land. The construction land can be saved 25.24 ten thousands hectares by 2020, in which transposition potential was 18.66 ten thousands hectares and potential from idle and waste land was 6.58 ten thousands hectares. In the future,the land use of construction would be put on internal exploitation of existing construction land. Meanwhile, unlimited urban sprawl and the area of rural residential land must be controlled gradually. The research can provide a decision-making basis for land use planning and land consolidation planning in the future.
