规划调控下的农村居民点整治潜力测算研究

Estimation of the consolidation potential of rural residential land based on planning regulation

农村居民点整治潜力测算是土地整治的重要内容,也是土地整治规划的核心环节。在乡镇土地利用总体规划调控下,将农村居民点划分为城镇化型及非城镇化型两大类;针对非城镇化型,构建农村居民点综合影响力评价指标体系,评价其综合影响力,并结合乡镇土地利用总体规划相关规定,将其划分为内部改造型、原地优化型及迁村并点型;根据不同整治类型,采用模式法构建相应的整治潜力测算模型。并以宜城市小河镇为例进行实证研究,预计到2020年小河镇通过整治可释放潜力117.83hm^2。本研究将为农村居民点整治潜力测算提供新的思路。

Potential estimation is important to rural residential land consolidation and critical to its planning. Previous work has focused on how to estimate consolidation potential accurately,but research has ignored the control of overall land use planning. Here,we classified rural residential land as rural urbanization and non-urbanization under the regulation of overall land use planning at the town level. For non-urbanization we constructed an evaluation index system for comprehensive influence in terms of three aspects（spatial layout suitability,production and living facilities accessibility,and rural residential land activity）and evaluated the comprehensive influence of rural residential areas. Based on that,and combined with relevant provisions of township land use planning,we divided rural residential land non- urbanization into internal transformation,optimization in place and village relocation and combination. We estimated land consolidation potential using the Type method,that is,according to different consolidation types we respectively constructed the relevant potential estimation model of land consolidation,Volume Ratio Method for rural urbanization,Idle Land Ratio Method for internal transformation,and Per Capita Construction Land Use based on the Household Willingness Method for village relocation and combination. Xiaohe Town in Yicheng City was our case study and we found a release potential of 117.83hm^2 through consolidation by 2020. The research will initiate new ideas for estimating land consolidation potential in rural residential areas.
