106国道沿线样带区农村空心化土地整治潜力研究

基于典型调查资料和社会经济统计数据,在构建农村空心化评价指标体系并定量评判106国道沿线样带区县域农村空心化程度的基础上,结合自然条件和土地资源特点、农村居民点用地的有关法律规定,采用专家集成法选取与现实潜力转化有关的自然、社会、经济等10个指标建立综合指标体系,对空心村整治的自然适宜性、社会接受性、经济可行性进行了综合评价;将计算得到的农村空心化指数与现实转化潜力系数作为综合修正系数,对理论潜力进行修正,结合农村居民点整治潜力测算公式,测算出106国道沿线样带区不同农村空心化演进类型的现状潜力和远景潜力。研究表明:106国道沿线样带区县域农村空心化指数为0.18~0.82,现实转化潜力系数为0.07~0.32; 2009、2020年农村居民点整治的现实潜力分别为93 219.4、145 430.0 hm²,村庄整治增地率分别为6.8%、11.4%。研究将为空心村整治和新农村建设规划决策提供科学依据。

Rural Land Consolidation Potential of Typical Transect along No.106 State Road

With the acceleration of industrialization and urbanization, there is a phenomenon of hollowing villages resulting from the vacancy and idleness of rural housing in the core of villages in the vast rural areas of China. In this paper, typical transect along No.106 State Road with obivious gradients both in the condition of physical environment and in the level of socioeconomic development is taken as a study. Its total area mounts to 0.155 million km². The rural land consolidation potential in transect along No.106 State Road is estimated as follows: Firstly, the comprehensive index of rural hollowing was evaluated by using the analytic hierarchy process (AHP) method and standardized method, based on typical survey-based data and socioeconomic statistics. Secondly, considering natural conditions, characteristics of land resources and the relevant legal provisions for rural residential land, a realistic transformation potential evaluation index system was established by the 10 indexes relating to natural, social and economic factors to calculate the realistic transformation potential index of rural land consolidation. Finally, by multiplying rural hollowing index and realistic transformation potential index as comprehensive correction coefficient to make the correction of the theoretical potential, the status quo potential and long-term potential of rural land consolidation were achieved based on potential calculation model. The stragety to consolidate rural land for various rural land consolidation potential areas in transect along No.106 State Road is also given. The results showed that the correction coefficient of rural hollowing in typical transect area along No.106 State Road was 0.18-0.82 and the correction coefficient of realistic transformation potential was 0.07-0.32. The comprehensive potential of rural land consolidation was 93219.4 hm² in 2009 and 145430.0 hm² in 2020, and the coefficient of increasing arable land was 6.8% in 2009 and 11.4% in 2020, respectively. This study will provide a scientific basis for hollow village renovation and new rural area construction planning decisions.
