Abstract:
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.
