农村居民点用地整治潜力测算研究——以广东省五华县为例

以广东省五华县为例,以行政村为单元,在政策指标测算法的基础上,从自然环境状况、经济保障能力和社会因素等3方面构建理论潜力修正模型,将理论潜力修正为可实现潜力,并根据土地适宜性评价估算增加耕地潜力,以期为科学编制农村土地整治规划提供依据。研究表明,五华县农村居民点用地布局分散、规模小、空间差异显著,呈现出沿河谷、沿交通线路分布的典型特征。到2020年,农村居民点整治理论潜力为5683.91 hm²,北部村庄的整治潜力较大;可实现潜力修正系数为0.54,与理论潜力相差较大,各行政村之间差异明显;新增耕地潜力系数介于0.32-0.94,预计新增耕地1943.41 hm²,琴江、五华河沿线村庄的新增耕地潜力较大。建议实施差别化的农村居民点整治对策,推进五华县农村土地整治。

EVALUATION OF RURAL RESIDENTIAL LAND CONSOLIDATION POTENTIAL: A CASE STUDY OF WUHUA COUNTY IN GUANGDONG PROVINCE

The orderly implementation of rural land consolidation is helpful to realize the protection of arable land red line and urban-rural harmonious development. Estimation of rural residential land consolidation potential is needed for the scientific establishment of rural land consolidation planning. Taking Wuhua County of Guangdong Province as an example, administrative villages as units, theoretical potential that calculated by the per capita construction land use standard method is modified into real potential by correction model including natural environment, economic support ability and social factors; then it calculates the increasing arable land potential in accordance with the assessment of land suitability. The following results are obtained:firstly, the rural residential land area in Wuhua County in 2010 is 14463.04 hm², mainly distributing in Hedong Town, Huacheng Town, Anliu Town, Hengpi Town and Longcun Town. Secondly, the theoretical potential of rural residential land consolidation in 2020 is 5683.91 hm², and the villages with higher theoretical potential are gathering in the northern of Wuhua County. Finally, four type zones, including urban polymerization area, key village construction and grass-root village relocation area, ecological key village construction area and removal-merger construction area, came into being based on the comprehensive assessment values and relevant planning.
